2-amino-4-hydroxy-6-methoxymethyl-5-methylpyrimidine (2.7 g, 16 mmol) was added to 20% aqueous hydrochloric acid solution (7 ml), and heated to 70° C. A solution of sodium nitrite (2.3 g, 33.3 mmol) in water was added dropwise to a reaction mixture while maintaining the reaction temperature under 70° C. The reaction mixture was cooled to a room temperature. The resulting solid was filtered and dried to give 1.5 g of the titled compound.
