Reaction Steps

4,6-dichloro-2-methylpyrimidine (2-1) (137.8 g, 845 mmol), 3,5-dimethyl-1H-1,2,4-triazole (2-2) (82 g, 845 mmol), and Cs2CO3 (275 g, 845 mmol) were suspended in DMF (1 L) and the resulting mixture was stirred at room temperature for 66 h. The mixture was then poured into water (2 L) and stirred for 1 hour. The precipitate was filtered, washed with water (2×) and dried under vacuum to afford Intermediate 2 as an off-white solid (130 g, 69%). MS: m/z=224.2 (M+H).
