Reaction Steps

A mixture of 4,6-dichloro-2-methylpyrimidine (505 mg, 3.1 mmol), 3,5-dimethyl-1H-1,2,4-triazole (300 mg, 3.1 mmol) and Cs2CO3 (1.54 g, 4.7 mmol) in THF (20 mL) was heated at reflux overnight. The mixture was filtered and the filtrate was concentrated to give 4-chloro-6-(3,5-dimethyl-1H-1,2,4-triazol-1-yl)-2-methylpyrimidine that was used without further purification. MS: m/z=224.1 (M+H).
