✦ Synopsis

The cyclization of 4-aryl-1-arylsulfonylthiosemicarbazides 3, which were prepared by treatment of arylsulfonyl chlorides 1 with 4-aryl-3-thiosemicarbazides 2, with chloroacetyl chloride, provided the corresponding 2-arylamino-4-arylsulfonyl-4H-1,3,4-thiadiazin-5(6H)-ones 4 in good yields. The structures of all these compounds were evaluated by elemental analyses, and 1 HNMR, and IR spectroscopy. The structure of compound 4f was ascertained by X-ray diffraction analysis.
