Procedure

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)benzenesulfonyl isocyanate. 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.
