Methyl-6-methoxypyridine-2-carboxylate (2 g, 11.96 mmol) in anhydrous methanol (20 mL) was cooled to 0° C. under nitrogen and sodium borohydride (1.36 g, 35.89 mmol) was slowly added to the solution. The reaction was left stirring at 0° C. for 30 minutes, then allowed to warm up to room temperature for 1 hour. The reaction was quenched with water and concentrated on the rotovap. The reaction was diluted with brine (100 mL) and extracted with dichloromethane/2-propanol solution (2:1) (3×, 150 mL). The combined organic extracts were dried over magnesium sulfate, filtered and concentrated on the rotovap to afford (6-methoxypyridin-2-yl)methanol (500 mg, 30%) as an oil. MS M+H calculated 140.1; found 140.1.
