Definitions
- the present invention relates to a process for producing 4-1- (methylthio) butane-1,2-diol.
- 4- (Methylthio) butane-1,2-diol is an important compound as a pharmaceutical intermediate or methionine analog (eg, European Patent No. 3 3 8 7 3 5, J. Agr i Food Chera , 23, 1 137 (1975)).
- a method for producing such 4- (methylthio) butane-1,2-diol J. Agric. Food Chem., 23, 1 137 (1975) includes 3-butene-1,2,2-diol.
- a method of reacting methanethiol with tert-butyl perphthalate is disclosed in European Patent Application No. 1 2 6 0 5 0 0 as 3-butene-1,2-diol and methanethio Each method is described in the presence of a boron compound.
- the present invention relates to a process for producing 4- (methylthio) butane-1,2-diol, which comprises reacting 3-butene-1,2-diol with methanethiol in the presence of a azo compound. It is to provide.
- 3-butene-1,2-diol may be used, for example, a method of reacting 1,2-epoxy-1-3-butene with water in the presence of a sulfuric acid catalyst (for example, US Patent First See 5 2 5 0 7 4 3 publication. ), A method of isomerizing 2-butene-1,4-diol in the presence of a dirhenium heptoxide catalyst (see, for example, US Pat. No. 5 3 3 6 8 15). You may use what was manufactured.
- methanethiol a commercially available product may be used, or a product produced from methanol and hydrogen sulfide may be used.
- methanethiol a gaseous one or a liquid one may be used.
- Liquid methanethiol can be prepared by, for example, a method in which gaseous methanethiol is introduced into a container cooled below its boiling point (at 6) and condensed.
- the amount of methanethiol used is usually more than 1 mole times that of 3-butene-1,2-diol, and there is no particular upper limit, but considering the economic aspect, it is practically 3— It is 10 mol times or less with respect to butene-1,2-diol.
- Azonitrile compounds such as azobisisobutanol diacetate, methyl azobisisobutyrate, and ethyl azobisisobutyrate; 2, 2'-azobisidine compounds such as diazobis 2 '-Azobis [2— (2-Imidazoline —2-yl) propane] and other azoimidazole compounds; 1, azobisboramide, 1, 1' Azoamide compounds such as azobis (N, N-dimethylformamide); azoalkyl compounds such as azo-tert-butane; and the like.
- Azonitrile compounds, azoester compounds, azoamidine compounds and azoimidazolines are preferred.
- azo compound a commercially available one is usually used.
- the amount of azo compound used is usually 0.01 mol or more of 3-butene-1,2-diol, and there is no particular upper limit, but considering the economical aspect, it is practical. Specifically, it is 0.2 mol times or less with respect to 3-butene-1,2-diol.
- the reaction between 3-butene-1,2-diol and methanethiol is usually carried out without solvent, but it may be carried out in the presence of a solvent.
- the solvent is not particularly limited as long as it does not inhibit the reaction, and water; hydrocarbon solvents such as hexane, heptane and toluene; halogenated hydrocarbon solvents such as chlorobenzene and chloroform; jetyl ether; An ether solvent such as methyl tert-butyl ether or tetrahydrofuran; an ester solvent such as ethyl acetate; a tertiary alcohol solvent such as tert-butanol; a nitrile solvent such as acetonitrile or propionitrile; Can be mentioned.
- the amount of such a solvent used is not particularly limited, but is practically less than 10 times the weight of 3-butene-1,2-diol in terms of volumetric efficiency.
- the reaction temperature varies depending on the type of azo compound used and the amount used, but if the reaction temperature is too low, the reaction does not proceed easily. If the reaction temperature is too high, 3-butene-1, 2— Since side reactions such as polymerization of diols and products may proceed, the reaction is usually carried out in the range of 10 to 100, preferably in the range of 0 to 50.
- the reaction is usually carried out under normal pressure or pressurized conditions. You may implement under pressure reduction conditions.
- the reaction between 3-butene-1,2-diol and methanethiol is carried out by mixing 3-butene-1,2-diol with methanethiol in the presence of an azo compound.
- an azo compound There is no particular limitation.
- When the reaction is carried out under ordinary conditions usually a mixture of a azo compound and 3-butene-1,2-diol is adjusted to a predetermined temperature, and gaseous methane thiol is blown into the mixture. The reaction is carried out.
- a azo compound and 3-butene-1,2-diol are added to a sealable container such as an autoclave and the container is sealed.
- a method of press-fitting gaseous methanethiol at a predetermined temperature; an azo compound, 3-butene-1,2-diol and liquid methanethiol are added to the sealed container;
- the reaction is carried out by a method of adjusting to the above.
- 3-butene-1,2-diol, methanethiol and azo compound are mixed and then reacted at a predetermined temperature, or 3-butene-1,2, diol and methanethiol are mixed.
- methanethiol in a mixture containing 3-butene-1,1,2-diol and methanethiol is converted to 3-butene-1, It is preferable to set it to 4 mol times or less with respect to 2-diol.
- the progress of the reaction can be confirmed by ordinary analytical means such as gas chromatography, high performance liquid chromatography, thin layer chromatography, nuclear magnetic resonance spectrum analysis, infrared absorption spectrum analysis.
- a lipophilic azo compound When a lipophilic azo compound is used after the completion of the reaction, for example, after removing the remaining methanethiol from the reaction mixture, water and a non-polar solvent are added as necessary, followed by extraction treatment. By concentrating the aqueous layer containing 4- (methylthio) butane-1,2-diol, the 4- (methylthio) butane-1,2-diol can be extracted.
- a hydrophilic azo compound for example, after removing residual methanethiol from the reaction mixture, water or an organic solvent insoluble in water is added and extracted as necessary.
- 4- (methylthio) butane-1,2-diol By concentrating the organic layer containing 4- (methylthio) butane-1,2-diol, 4- (methylthio) butane-1,2-diol can be extracted.
- Examples of a method for removing remaining methanethiol from the reaction mixture include a method of concentrating the reaction mixture, a method of blowing an inert gas such as nitrogen gas into the reaction mixture, and the like.
- the nonpolar solvent include hydrocarbon solvents such as hexane, heptane, toluene, and xylene, and the amount used is not particularly limited.
- the water-insoluble organic solvent include, in addition to the hydrocarbon solvent, an ester solvent such as ethyl acetate, an ether solvent such as methyl tert-butyl ether, and the amount used is not particularly limited.
- Example 4 the same procedure as in Example 4 was performed except that 2,2′-azobis [2- (2-imidazoline-2-yl) propan] was used instead of methyl azobisisobutyrate. A solution containing methylthio) butane-1,2-diol was obtained. The yield of 4- (methylthio) butane-1,2-diol was 98%.
