Abstract

The invention comprises compounds of the general formula: <FORM:0873777/IV (b)/1> wherein R1 and R2 are hydrogen atoms or a C1-C6 alkyl group and R3 represents a C1-C6 alkyl group, and the preparation thereof by heating a compound of the general formula: <FORM:0873777/IV (b)/2> wherein R is an alkyl or aralkyl group with an alkyl a -nitroalkanoate in the presence of an inert solvent to obtain the correspondingly substituted alkyl a -alkyl-a -nitro-3-indolepropionate, reducing the latter compound, after N-alkylation if desired in the case where R1 is hydrogen, to yield the corresponding alkyl ester of 5-substituted hydroxy-a -alkyl-tryptophane, hydrolysing the latter compound, and subjecting to hydrogenolysis where R is aralkyl or to dealkylation where R is alkyl. The compounds of the invention form salts with acids and bases both inorganic and organic. 5-Benzyloxy-1-methylgramine is prepared by reacting 5-benzyloxyindole with dimethylformamide and phosphorus oxychloride to form 5 - benzyloxy - 3 - indolecarboxyaldehyde methylating this to form 1-methyl-5-benzyloxy-3-indolecarboxyaldehyde, oxidising the aldehyde to 1 - methyl - 5 - benzyloxy-3-indolecarboxylic acid, decarboxylating the acid to 1-methyl-5-benzyloxyindole and reacting the indole with formaldehyde and dimethylamine. 5-Benzyloxy-2-methylgramine is prepared from 5-benzyloxy-2-methylindole, formaldehyde and dimethylene. Specification 744,774 and U.S.A. Specifications 1,915,334, 2,075,359, 2,425,320, 2,557,041, 2,606,155, and 2,616,896 are referred to.ALSO:Pharmaceutical compositions comprise a compound of the general formula <FORM:0873777/VI/1> wherein R1 and R2 are hydrogen or C1-6 alkyl groups and R3 is a C1-6 alkyl group or a salt thereof with an organic or inorganic acid or base, together with a solid or liquid diluent. The compositions may include tablets, capsules, powder packets, or suspensions or solutions in suitable solvents for oral or parenteral administration.
