In continuing our work on sulfabenzothiazoles containing salt-forming groups, 2-sulfanilylamino-benzothiazole 6- and 5-(or 7-)carboxylic acids were obtained. Their sodium salts are very soluble in water and give neutral solutions. Through the same route,it failed to synthesize the corresponding 4-carboxylic acid,starting either from anthranilic acid or its ethyl ester.They did not give o-thioureidobenzoic acid or its ester,but cyclized to benzoylene thiourea(2- sulfhydryl 4-hydroxyl quinazoline).The same compound...

In continuing our work on sulfabenzothiazoles containing salt-forming groups, 2-sulfanilylamino-benzothiazole 6- and 5-(or 7-)carboxylic acids were obtained. Their sodium salts are very soluble in water and give neutral solutions. Through the same route,it failed to synthesize the corresponding 4-carboxylic acid,starting either from anthranilic acid or its ethyl ester.They did not give o-thioureidobenzoic acid or its ester,but cyclized to benzoylene thiourea(2- sulfhydryl 4-hydroxyl quinazoline).The same compound was obtained from the hydrolysis of α-o-carboxyphenyl β-benzoyl thiourea and from the ammoniolysis of o-isothiocyanobenzoic acid. Attempt to cyclize α-o-carboxyphenyl β-benzoyl thiourea by bromine to 2- benzamido-benzothiazole 4-carboxylic acid also failed,and the desulfured cyclized compound was identified to be 2-benzoyl benzoylene urea. We have,at the same time,cleared up the diversed results of H.Rupe and G.M.Dyson et al.and identified the structure of the Douglass and Dains' compound.
