Abstract

The present invention discloses method of preparing N-orthobutyl benzoyl-2-sulfonylendo imine, it includes that under the existance of phase transfer catalyst and in the phydrocarbon solvent, to proceed reaction between benzosulfimide and alkyl halide.

Description

The preparation method of N-n-butylbenzene formyl-2-sulfonyl inner imine
The present invention relates to the method for a kind of synthetic N-n-butylbenzene formyl-2-sulfonyl inner imine, utilize phase-transfer catalyst exactly in the solid-liquid two-phase, with the saccharin sodium one-step synthesis N-n-butylbenzene formyl-2-sulfonyl inner imine that contains crystal water.N-n-butylbenzene formyl-2-sulfonyl inner imine is for having following structural A kind of white crystal.
The existing technology of preparation N-n-butylbenzene formyl-2-sulfonyl inner imine is the alkylating reagent saccharin sodium reaction good with pulverizing drying treatment in advance, manys pulverizing and dry two procedures than the present invention, and is time-consuming also uneconomical.
At the shortcoming of prior art, the present invention proposes improving one's methods of a kind of N-of production n-butylbenzene formyl-2-sulfonyl inner imine.According to the present invention, this compound is that directly usefulness contains the saccharin sodium and the alkylating reagent reaction of crystal water and makes.
The used phase-transfer catalyst of the present invention is Tetrabutyl amonium bromide, triethyl benzyl ammonia chloride, cetyl trimethylammonium bromide, polyoxyethylene glycol, Zeo-karb etc., preferably Tetrabutyl amonium bromide.Catalyst levels is 2%~7% mole, is preferably 5% mole.
The used alkylating reagent of the present invention is a bromination of n-butane, and the mol ratio of this alkylating reagent and saccharin sodium is 0.7~1.4, preferred ratio 1.1.
The reaction required time of the present invention time more required than prior art is wanted much shorter, has simplified the purifying formality, makes operation more simple and easy to do.
The productive rate of N-n-butylbenzene formyl of the present invention-2-sulfonyl inner imine is up to more than 95%.And prior art will be 86.2% (Zhong Qi with the prior productive rate of pulverizing the good saccharin sodium of drying, chemical reagent 198810 (1) 47~48) and 90% (Celso F.Perez, Organic Prepartions and Procedures INT16 (1) 37~41,1984).
Reaction process of the present invention does not need other monitoring, and for example whether the thin-layer chromatography monitoring reaction carries out fully.The present invention then determines reaction process according to aquifer yield in reaction process.Save the operation of other detection.
Another advantage of the present invention is the reaction yield height, and generally between 96%~98%, product purity is also high for productive rate, 98%~99%, and mp39~41 ℃.
Be reflected in the four-hole bottle and carry out, this four-hole bottle is equipped with agitator, thermometer, water trap and reflux cooler.
Embodiment one:
In being housed, 1000 milliliters of four-hole bottles of agitator, thermometer, water trap and reflux cooler add o-benzoic sulfimide sodium salt (C 7H 4O 3NSNa2H 2O) 121 grams (0.5mol), 350 milliliters of toluene, reflux, after minute water outlet is near 18 milliliters, stop heating, after reacting liquid temperature drops to below 80 ℃, add Tetrabutyl amonium bromide (TBAB) 8 grams respectively, 54 milliliters of bromination of n-butane, heating reflux reaction 12 hours stops heating, after reaction mixture drops to below 85 ℃, add 100 milliliters in water, stirred standing demix, branch vibration layer 30 minutes.Behind the oil reservoir pressure reducing and steaming toluene, 134~136 ℃/23-30Pa cut is collected in rectification under vacuum, product 117 grams, mp40~41 ℃, productive rate 97.4%.
Embodiment two:
In 1000 milliliters of four-hole bottles of agitator, water trap, thermometer and reflux cooler are housed, add o-benzoyl sulfonyl inner imine sodium salt (C 7H 4O 3NSNa2H aO) 242 grams, 650 milliliters of toluene.Reflux three hours, tell 35 ml waters after, stop heating, reacting liquid temperature drops to below 80 ℃ the back and adds cetyl trimethylammonium bromide (HTMAB) 18 grams, 110 milliliters of bromination of n-butane.Reflux 12 hours, stop the heating, cool to below 85 ℃ after, add 200 milliliters in water, stir after 30 minutes, standing demix discards water layer, oil reservoir pressure reducing and steaming toluene, rectification under vacuum, 134~136 ℃/25~30Pa of collection slips and divides, and gets product 227.1 grams, productive rate 95%.mp40℃~41℃。
Embodiment three:
Measure the short effect of oozing of N-n-butylbenzene formyl-2-sulfonyl inner imine.
With φ=75% ethanol preparation 1.67GBqL -1 3The contrast liquid of H-Berberine is got 1.92mL 3H-Berberine contrast liquid adds the azone soup that 80 μ L azones are mixed with φ=4%, uses the N-n-butylbenzene formyl-2-sulfonyl inner imine soup that contains φ=4% with the quadrat method preparation.Get 10 of mouse, losing hair or feathers with trichogen in the back, exposes skin, gets the back that 1.5cm * 1.5cm gauze is layered on the depilation mouse open and flatly, gets 3H-Berberine contrast liquid 100 μ L evenly coat on the gauze, use immobilization with adhesive tape then, get blood 20 μ L respectively at 0.5,1,2,4,6,12,24 hour from mouse socket of the eye vein and place small test tube, add formic acid, H 2O 2Each 100uL is at 60 ℃ of digestion 30min.Get Digestive system 100uL and add and to have surveyed background and be added with in the scintillation vial of 7mL scintillation solution, place liquid to dodge spectrometer and measure, measure 10min, with F TSIECarrying out DPM for the quench correction factor restores.With with quadrat method replication φ=4% azone and φ=4%N-n-butylbenzene formyl-2-sulfonyl inner imine sample sets, its result such as table 1.
Table 1N-n-butylbenzene formyl-2-sulfonyl inner imine and the short effect of oozing of azone.
Sample Contrast Azone N-n-butylbenzene formyl-2-sulfonyl inner imine
S/GBq·L -1h -1 ?9.168 ??35.388 ???????????106.016
???S/S Contrast ?1.00 ??3.86 ???????????11.56
???S/S Azone ?- ??1.00 ???????????2.99
Azone can improve 3.86 times of the bioavailabilities of the Berberine of transdermal administration as shown in Table 1, and N-n-butylbenzene formyl-2-sulfonyl inner imine can improve 11.56 times.This shows that N-n-butylbenzene formyl-2-sulfonyl inner imine has the stronger short effect of oozing than azone, and it is short, and to ooze effect be 2.99 times of azone.
