실험 절차

1.6 g (0.01 mol) of 2-amino-4-chloro-6-methoxypyrimidine are dissolved in 30 ml of dichloromethane, and 2.7 g (0.01 mol) of 1-pyrrolidinosulfonylethylsulfonyl isocyanate (Example 3b) in 30 ml of dichloromethane are added dropwise at room temperature. After the mixture has been stirred for 3 hours at room temperature, the organic phase is washed with 2N HCl and water, dried and evaporated. Trituration of the crude product with diethyl ether gives 30 g (70% of theory) of 3-(4-chloro-6-methoxypyrimidin-2-yl)-1-(1-pyrrolidinosulfonylethylsulfonyl)urea of melting point 158°-160° C.
