Reaction Steps

Crude sodium salt of 4-amino-5-nitroso-2-(2-phenylethyl)pyrimid-6-one (3.8 g.) was dissolved in water (5.5 ml.). A trace of insoluble material was filtered off, and sodium dithionite (4.08 g.) was added slowly to the filtrate with stirring. The solid which separated was filtered off, washed with water, and recrystallised from ethanol to give 4,5-diamino-2-(2-phenylethyl)pyrimid-6-one (0.75 g.), m.p. 204°-206° C. (with decomposition).
