6-Amino-3-methyluracil Use and Manufacturing

6-Aminouracil (5) (5.18 g, 40.7 mmol) was suspended in HM DS (25 mL) and HStep 1 6-amino-3-methylpyrimidine-2, 4(lH, 3H)-dione To a solution of the 6-aminopyrimidine-2, 4(lH, 3H)-dione (15 g, 1 18 mmol) in 1 , 1 , 1 , 3, 3, 3- hexamethyldisilazane (50 mL) was added ammonium sulfate(0.671g, 5 mmol), then the resulting mixture was heated to reflux with stirring for 6 h. The mixture was concentrated to give a light-yellow solid. This solid was combined with acetonitrile (50 mL) and iodomethane (15 mL, 250 mmol) was added. The resulting mixture was stirred at 40 °C for 16 h. Then the mixture was concentrated, neutralized with saturated sodium bicarbonate to pH =7, filtered, and the filter cake was washed with brine and ethanol, dried under vacuum to give 6-amino-3- methylpyrimidine-2, 4 (lH, 3H)-dione (7.1 g, 42.6 percent yield) as yellow solid.
