To 0.7 g of 2-amino-4,6-dimethoxy-1,3,5-triazine in 10 ml anhydrous methylene chloride solvent was added 1.45 g 2-(β-chloroethoxycarbonyl)benzenesulfonylisocyanate. After stirring at ambient temperature for sixteen hours the solvent was removed under reduced pressure, the residue triturated with ether and the solid product filtered off, yield 1.21 g m.p. 171°-174° C. The solid showed infrared absorption peaks at 1705 and 1715 cm-1, consistent for N-[(4,6-dimethoxy-1,3,5-triazin-2-yl)aminocarbonyl]-2-(2-chloroethoxycarbonyl)benzenesulfonamide.
