Procedure

To a stirred mixture of 0.8 g of 2-methylamino-4-methoxy-6-methylpyrimidine in 25 ml of acetonitrile containing a few crystals of 1,4-diazabicyclo[2.2.2]octane was added dropwise 1.3 g of 2,5-dichlorobenzenesulfonyl isocyanate. The mixture was stirred for 16 hours and the resultant solid was filtered to afford 1.2 g of N-[N-(4-methoxy-6-methylpyrimidine-2-yl)-N-methylaminocarbonyl]-2,5-dichlorobenzenesulfonamide melting at 182°-185°. Infrared absorption spectrum showed peaks at 1690 cm-1, 1590 cm-1, and 1550 cm-1 which are typical for this type of compound.
