Reaction Steps

A stirred mixture of commercially available 2-amino-5-cyano-pyrimidine [CAS-No. 1753-48-6] (1.39 g, 11.6 mmol), hydroxylamine hydrochloride (1.61 g, 23.2 mol) and potassium carbonate (4.8 g, 34.7 mol) in ethanol (57 ml) was heated under reflux conditions for 3 h. The reaction mixture was evaporated and purified by column chromatography on silica gel (dichloromethane/MeOH 9:1) to yield the title compound (1.28g, 72%) as an off-white solid. MS (EI) 153.1 [(M)+]; mp 218° C.
