Abstract
The α-methylene group of the side chain of 4-methyl(phenyl)-2-arylsulfonylmethylthiazoles and 5-arylsulfonylmethyl-1H-tetrazoles is inactive in electrophilic substitution with arenediazonium salts, but the former react with aryl isocyanates to give arylamides of 2-[4-methyl(phenyl)thiazolyl]arylsulfonylacetic acids. The stability of the reaction products was confirmed by independent synthesis of the expected products.
