2-Amino-4,6-dimethoxypyrimidine → N-[(4,6-Dimethoxypyrimidin-2-yl)aminocarbonyl]-2-(dimethylaminosulfonyloxy)benzenesulfonamide

Participants

Reaction Steps

To a suspension of 0.46 g (0.003 mole) 2-amino-4,6-dimethoxypyrimidine in 5 ml methylene chloride was added 1.2 g (0.004 mole) 2-(dimethylaminosulfonyloxy)-benzenesulfonyl isocyanate. The reaction exothermed (18°-26° C.) and was then stirred at room temperature 3 hours. The solvent was evaporated under reduced pressure. The resultant mixture was triturated with diethyl ether and filtered to give 1.2 g of a white solid, m.p. 165°-168° C. The infrared spectrum shows absorption bands at 1710, 1380, 1170 cm-1.
