Procedure

A mixture of 2-amino-4-methoxy-6-methylpyrimidine (0.45 g, 3.2 mmol), methylene chloride and DABCO (ca. 10 mg) was contacted with 2-(1-cyclopentenyl)benzenesulfonyl isocyanate in methylene chloride solution at ambient temperature. After approximately 20 minutes the product crystallized from the reaction mixture and was collected by filtration and rinsed with ether. In this manner, 0.35 g of product was obtained, m.p. 235°-236°. The infrared spectrum exhibited a carbonyl absorption at 1710 cm-1 indicating the title compound.
