Participants

Reaction Steps

A mixture of 1 g of 2-amino-4-dimethylamino-6,7-dimethylpteridine and 1.3 g of 2-carbomethoxyphenylsulfonyl isocyanate was stirred in 10 ml of acetonitrile for 30 minutes at room temperature and then the mixture was heated to reflux for 3 to 4 minutes. After cooling diisopropyl ether was added thereto and the mixture was vacuum filtered to obtain 1.7 g (81% of theory) of N-(4-dimethylamino-6,7-dimethylpteridin-2-yl)-N'-(2-carbomethoxyphenylsulfonyl)-urea melting at 196° C.
