4(1H)-Pyrimidinone,2-amino-6-methyl-5-nitro- Use and Manufacturing

2-Amino-6-methyl-5-nitropyrimidin-4(3H)-oneTo a mixture of 2-amino-6-methylpyrimidin-4(3H)-one (50 g, 0.4 mol) in 250 mL of HIn a two-neck round-bottom flask containing precooled sulfuricacid (3 mL) was added 2-amino-4-hydroxy-6-methylpyrimidine(1) (100 mg, 0.8 mmol). An effective temperature control isrequired to the nitration occur properly. Nitric acid (0.2 mL, 3.0 mmol) was added to the solution dropwise maintaining thetemperature below 6 C using an ice bath. The mixture waswarmed to room temperature and stirred for 3 h. The reaction mixturewas added in cold ethyl ether (10 mL), remaining the temperaturebelow 10 C. The precipitate was filtered and dissolved inboiling 1 mol/L NaOH solution. Acetic acid was added to the solutionfor precipitation of the product (pH among 6–8). The solid wasfiltered under vacuum, washed with water (2 1 mL) and dried invacuum for 8 h. The pyrimidinone 2 was obtained in 69percent yield(117 mg)
