Procedure
To a dry stirred solution of 0.5 g of 4,6-dimethylfuro[2,3-d]pyrimidin in 10 ml of acetonitrile at ambient temperature and pressure was added 1.6 g of 2-carbomethoxybenzenesulfonyl isocyanate. The resulting mixture was warmed on the steam bath for several minutes then stirred at ambient temperature for 4 hours. The suspended solid was collected by filtration and rinsed with acetonitrile to yield 0.87 g of methyl 2-{[(4,6-dimethylfuro[2,3-d]pyrimidin-2-yl)aminocarbonyl]aminosulfonyl}benzoate, m.p. 197°-198°. The product showed characteristic absorption bands at 1690 and 1735 cm-1 in the infrared spectrum and at 2.45, 2.75, 3.95, 6.6, 7.7, 8.3, 10.4 and 13.0 ppm in the nuclear magnetic resonance (60 MHz) spectrum indicating the title compound.
