✦ Synopsis

The cyclization of 4-arnino-5-(N-methyl-arylsulfonarnido) methyl-1,2,4-triazole-3-thiones 11, synthesized by the Reid and Heindel approach, with a-chloroacetophenone yields 7H-6-aryl-3-(N-rnethyl-arylsulfonarnido) methyl-s-triazob[3,4-b][l, 3,4]-thiazines 111.

Novel compounds I1 also react with benzyl chloride to afford 4-amino-3-benzyIthio-5-(N-rnethyl-arylsulfon- arnido)methyl-1,2,$-triazole IV.0 I996 John Wiley & Sons, Inc.
