Reaction Steps

Platinum oxide (50 mg, 0.22 mmol) was added to a solution of 2-(N-pentanoyl)amino-5-nitropyrimidine (650 mg, 2.9 mmol) in ethanol (100 ml) at ambient temperature and the reaction stirred for 1 hour under an atmosphere of hydrogen. The reaction was filtered through a pad of celite and the solvents were evaporated in vacuo. Trituration with diethylether and drying yielded 2-(N-pentanoyl)amino-5-aminopyrimidine (307 mg, 55% yield) as brown solid:
