Dabco → Benzene-1,2-disulfonamide

참여 물질

반응 단계

A mixture of 0.8 g of 2-amino-4,5,6-trimethylpyrimidine, 2.8 g of the crude sulfonyl isocyanate from Example 9 and a few crystals of DABCO in 25 ml of acetonitrile is stirred at room temperature for 16 hours. A small amount of unreacted aminopyrimidine is filtered off and the filtrate concentrated in-vacuo to give a hard glass. Crystallization from methanol gives N,N-diethyl-N'[4,5,6-trimethylpyrimidin-2-yl)aminocarbonyl]-1,2-benzenedisulfonamide as a white solid.
