Reaction Steps

To a solution of 6-chloro-1-isobutyl-3-methylpyrimidine-2,4(1H,3H)-dione (2.0 g 9.3 mmol) in EtOH (8 mL), hydrazine monohydrate (1.3 mL) in EtOH (3 mL) is added slowly. The reaction mixture is refluxed for 5 hours, and then cooled. A large amount of AcOEt is added into the reaction mixture, and then cooled and filtered to give 1.95 g of product as yellowish solids (Yield: 100%).
