Abstract

The ethyl ester and amides of 2H-1,2,4-benzothiadiazine-3-carboxylic acid 1,1-dioxide were obtained by reaction of 2-aminobenzenesulfonamide with diethyl oxalate or oxamic acid esters in the presence of sodium methoxide. The hydrolysis, animation, and hydrazinolysis of the ester were studied.
