Procedure

52.8 g (0.27 mol) of 6-amino-1-butyl-5-nitroso-2,4-(1H,3H)-pyrimidinedione (IX) was dissolved in 1 l of DMF at 90° C. and catalytically hydrogenated in the presence of 0.1 g PtO2 for 18 hours and at room temperature and at a pressure of 200 KPa. The catalyst and the crystals were filtered off and washed with ethanol. Yield 36.6 g (67%) (X), NMR.

Workup
