Studies on sulfonamides. Part II: preparation of ethyl 4-(2-arylsulfonamido-4-phenylsulfonyl-s-triazin-6-yl)aminobenzoate.In this study， 121-60-8 and 98-68-0 are also used. Goghari, M. H.; Parikh, A. R. (Dep. Chem., Saurashtra Univ., Bhavnagar, India). J. Indian Chem. Soc., 53(9), 946-7 (English) 1976. CODEN: JICSAH. DOCUMENT TYPE: Journal CA Section: 28 (Heterocyclic Compounds (More Than One Hetero Atom)) Triazinylaminobenzoates I (R = Ph, p-tolyl, p-MeOC6H4, p-ClC6H4, p-BrC6H4, p-IC6H4, p-AcNHC6H4, 1-, 2-naphthyl) were obtained in 60-70% yields in 4 steps from cyanuric chloride by treatment with PhSH, amination with p-H2NC6H4CO2Et, amination with NH3, and reaction with RSO2Cl. Oxidn. of I with KMnO4 gave 64-80% of the corresponding sulfones. .
