110 °C

To a solution of 2-hydroxy-4,6-dimethylpyridine-3-carbonitrile (85.0 g, 0.574 mol) and benzyl chloride (87.0 g, 0.688 mol) in toluene (800 mL) was added Ag2O (146 g, 0.631 mol). The reaction mixture was stirred at 110° C. overnight. The reaction mixture was filtered through CELITE® and the solids washed with CH2Cl2. The filtrate was concentrated under vacuum and purified by column chromatography (petroleum ether/EtOAc) to give 2-(benzyloxy)-4,6-dimethylpyridine-3-carbonitrile (Cpd W, 89 g, 65%) as a white solid.
