Reaction Steps

Platinum oxide (60 mg, 0.22 mmol) was added to a solution 2-(N-2-chlorobenzoyl)amino-5-nitropyrimidine (278 mg, 1.0 mmol) in ethanol (1 ml) and ethyl acetate (10 ml) at ambient temperature and the reaction stirred for 3 hours under an atmosphere of hydrogen. The reaction was filtered through a pad of celite and the solvents were evaporated in vacuo. Purification by flash chromatography on silica gel, eluting with 5% methanol in ethyl acetate yielded 2-(N-2-chlorobenzoyl)amino-5-aminopyrimidine (121 mg, 50% yield) as brown solid:
