Reaction Steps
A mixture of 4,6-dichloro-5-fluoro-2-methylpyrimidine (1.55 g, 8.6 mmol) in aqueous ammonium hydroxide (10.00 mL, 90 mmol) and MeOH (1.00 mL, 25 mmol) was heated at 70° C. for 2 h (sealed tube). After cooling, 10 mL water was added and stirred for 30 min. The solid was isolated, washed with water, and dried to give the desired product 6-chloro-5-fluoro-2-methylpyrimidin-4-amine (0.9244 g, 67%) as a white solid. MS (API-ES) m/z 163 (M+H)+.
