Procedure
A mixture of 4-amino-2-cyclohexylpyrimid-6-one (18 g.) and water (150 ml.) was stirred and heated to 70° C, and treated slowly with sodium nitrite (8 g.), followed by an excess of glacial acetic acid. The mixture was stirred for a further 1 hour and the blue solid (25 g.) filtered off and used directly for the next stage. A sample recrystallised from glacial acetic acid gave pure 4-amino-2-cyclohexyl-5-nitrosopyrimid-6-one, m.p. 233°-234° C. (with decomposition).
