Procedure
A 250 mL round bottom flask was charged with 5-bromo-2-chloro-4-hydrazinylpyrimidine (17 g, crude, 59.2 mmol) and 3 M HCl (600 mL). To the above was added dropwise a solution of NaNO2 (8 g, 0.1 mol) in water (15 mL) at 10° C. The resulting mixture was stirred at 10° C. for 1 h. Work-up: the resulting crystalline solid was collected by filtration. The solid was washed with ethanol (20 mL), and dried to afford 10 g (72%) of the product as a red solid.
