POTENTIAL NEUROLEPTICS OF THE ORTHOPRAMIDE SERIES; SYNTHESIS OF N-SUBSTITUTED 5-(AMINOSULFONYL)-2-METHOXYBENZAMIDES

The mixed anhydride of 5-(aminosulfonyl)-2-methoxybenzoic acid (VII) and monoethyl carbonate reacted with benzylamine, 1-methylpiperazine, and 1-benzylpiperazine to give the 5-(aminosulfonyl)-2-methoxybenzamides II, IV, and V.Heating the ethyl ester X with 4-amino-1-methylpiperidine resulted in the amide III.Reaction of 5-(chlorosulfonyl)-2-methoxybenzoyl chloride (XI) with 1-benzylpiperazine afforded 5-(4-benzylpiperazinosulfonyl)-2-methoxybenzoic acid 4-benzylpiperazide (VI).Compounds II-VI are analogues of the antidopaminergic and antiemetic agent sulpiride (I) but only the benzylpiperazides V and VI showed indications of psychotropic activity of the neuroleptic type.
