실험 절차
To a mixture of 1.10 g of 4-amino-2,6-dimethoxypyrimidin in 40 ml methylene chloride at ambient temperature and pressure was added 1.60 g of 2-chlorobenzenesulfonylisocyanate. The reaction was stirred 30 minutes and then refluxed an additional 15 minutes. Volatiles were removed under reduced pressure and the solid thereby obtained was washed with a little diethyl ether; yield 2.30 g, m.p. 193°-196°.
