Reaction Steps

In a dry flask under a nitrogen atmosphere was mixed 0.24 g of 2-amino-4-ethenyl-6-methylpyrimidine, 0.61 g of 2-carbomethoxybenzenesulfonylisocyanate and 25 ml of dry dichloromethane. The solution was heated to reflux for five minutes and allowed to stir at room temperature overnight. A precipitate formed. The reaction mixture was stripped, titurated with butyl chloride to give 0.56 g of the title compound as a solid, m.p. 185°-190° (dec); IR(nujol) 2111 (C≡C), 3250 (NH), 3321 (NH), 1716 (CO) and 1725 (CO) cm-1.
