Abstract

Abstract 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-methyl-piperidine resulted in the amide III. Reaction of 5- (chlorosulfonyl)-2-methoxybenzoyl chloride (XI) with 1-benzylpiperazine afforded 5-(4- ...
