Reaction Steps

Cyclohexanoyl chloride (1.05 g, 7.14 mmol) was added dropwise to a stirred suspension of 2-amino-5-nitropyrimidine (1.0 g, 7.14 mmol) in pyridine (10 ml) and the reaction was heated at reflux for 4 hours under an inert atmosphere. The reaction mixture was cooled then stirred in 2N hydrochloric acid (100 ml) and extracted with ethyl acetate. Crystallisation from ethyl acetate/hexane, yielded 2-(N-cyclohexanoyl)amino-5-nitropyrimidine (1.15 g, 64% yield) as a beige solid:
