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. Copyright Taylor & Francis Inc.
