Procedure
4-Methoxybenzyl alcohol (1.66 g, 12 mmol) was dissolved in DMF (20 mL). Potassium hydroxide (2.31 g, 36 mmol, 87%) was added and stirred at room temperature for 10 min followed by cooling to 0° C. 4,6-dichloro-2-methylpyrimidine (2.15 g, 13.2 mmol) was dissolved in DMF (4 mL) and added to the solution drop-wise. The internal temperature was controlled under 2° C. The reaction solution was kept at 0° C. for 2 h, then allowed to warm slowly to 16° C. over 1 hr. The reaction was diluted with ethyl acetate (50 mL), washed with brine (50 mL×2), dried over MgSO4, filtered and concentrated i. vac. The crude mixture was purified by chromatography on silica gel (eluting 7.7% ethyl acetate/hexane) to yield the titled compound as a colorless oil. LC-MS (M+1): 265.51, (M+23): 287.52.
