Procedure
2.4 g (0.008 mol) of 2-methoxycarbonyl-4-phenylthiophen-3-ylsulfonamide, 2.2 g of N-(4,6-dimethoxypyrimidin-2-yl)phenylcarbamate, 1.2 g of 1,8-diazabicyclo[5.4.0]undec-7-ene and 30 ml of acetonitrile are stirred for 16 hours at room temperature. The reaction mixture is then poured into a mixture of ice and water and acidified with methanesulfonic acid. The resultant precipitate is filtered, washed with water and dried, affording 3.4 g (95%) of N-(2-methoxycarbonyl-4-phenylthiophen-3-ylsulfonyl)-N'-(4,6-dimethoxypyrimidin-2-yl)urea with a melting point of 225°-227° C.
