To 3-bromo-5-methylpyridin-2-ol (500 mg, 2.7 mmol) and silver carbonate (2.6 g, 9.6 mmol) suspended in dichloromethane (10 mL) was added iodomethane (0.83 mL, 13 mmol). The reaction mixture was allowed to stir at room temperature overnight. The reaction mixture was filtered through a pad of celite and the volatiles were evaporated to yield 3-bromo-2-methoxy-5-methylpyridine, which was used directly in the next step. ESI-MS m/z calc. 201.0. found 202.3 (M+1)+. Retention time 1.51 minutes.
