A mixture of 2-chloro-4-methylpyridine (20 g, 0.156 mol) and NaOCH3 (9.3 g, 0.172 mol) in DMSO (200 mL) was stirred at 100° C. for 4 hours. The solution was added to H2O and then extracted with ethyl acetate (50 mL×2). The organic layer was washed with H2O (300 mL) brine (300 mL) and dried concentrated to give 2-methoxy-4-methylpyridine (9 g, 46%). LC-MS: 124 [M+H]+, tR=1.21 min.
