Participants

Reaction Steps

A suspension of 2-amino-4-chloro-6-hydroxy-5-nitropyrimidine (III) (Hal=Cl) (2.3 g) in dry ethanol was treated with 3-amino-1-hydroxy-3-spirocyclohexylpropan-2-one oxime hydrochloride (IV) (2.5g) and dry triethylamine (2.7 g) and the mixture was refluxed for 7 h. The reaction mixture was filtered and the solid washed with hot ethanol. The solvent was removed from the filtrate and the resulting yellow oil was triturated with cold water giving a yellow solid which on recrystallisation from water in the presence of charcoal gave the nitropyrimidine (II) (1.85 g; yield 47.4%) as an off-white powder, m.pt >300° (decomp.).
