실험 절차

A microwave vial was charged with 4,6-dichloro-2,5-dimethylpyrimidine (523 mg, 2.95 mmol) and ammonium hydroxide (8 mL) in ethanol (4 mL). The vial was heated to 80° C. and stirred for 8 h. After concentration under reduced pressure, the reaction mixture was extracted with EtOAc (15 mL×8). The combined organic layers were washed with brine (30 mL), dried over Na2SO4 and concentrated to give 6-chloro-2,5-dimethylpyrimidin-4-amine as a yellow solid (411 mg). MS (ESI): m/z 158 [M+H]+.
