Abstract

Abstract Reaction of thionyl chloride with semicarbazones of 1-(4-methylsulfonylphenyl)-2-(4- substituted pheny) lethanone gave 4-(4-methylsulfonylphenyl)-5-(4-substituted) pheny-1, 2, 3-thiadiazoles 5. Compounds 5-phenyl-4-(substitutedphenyl)-1, 2, 3-thiadiazoles 14 were similarly prepared. Chlorosulfonation of the latter followed by ammonia gave the desired compounds 5-(4-aminosulfonylphenyl)-4-(substituted) phenyl-1, 2, 3-thiadiazoles 6.
