Reaction Steps

To a solution of 4,6-dichloro-2-methylpyrimidine (10 g, 0.061 mol) in dry THF (500 ml) was added anhydrous hydrazine (1.96 g, 0.061 mol) followed by potassium carbonate (12.7 g, 0.092 mol). The reaction mixture was stirred at room temperature for 13 h and filtered. The filtrate was evaporated under reduced pressure to afford 9.3 g (45%) of the titled compound as a solid.
