실험 절차

A mixture of 6-chloro-5-methylpyridin-3-ol (250 mg, 0.0017 mol), 1-(chloromethyl)-4-methoxybenzene (0.328 g, 0.0020 mol, Sigma Aldrich), and potassium carbonate (0.482 g, 0.0034 mol) in DMF (5 mL) was allowed to stir for 3 h at 60° C. After completion of the reaction, reaction mixture was cooled to ambient temperature and poured into ice cold water (25 mL). The obtained solid was filtered, washed with water (2×10 mL) and dried to obtain 2-chloro-5-((4-methoxybenzyl)oxy)-3-methylpyridine as an off white solid (400 mg, 87%).
