2-Amino-4,6-dimethyl pyrimidine → N-[(4,6-Dimethylpyrimidin-2-yl)aminocarbonyl]-2-(dimethylaminosulfonyloxy)benzenesulfonamide

Participants

Reaction Steps

To a suspension of 0.37 g (0.003 mole) 2-amino-4,6-dimethylpyrimidine 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 stirred at room temperature for 3 hours. The resultant white precipitate was filtered to give 0.9 g of a white solid, m.p. 195°-196° C. The infrared spectrum shows absorption bands at 1705, 1380, 1180 cm-1.
