Procedure
A solution of methyl 6-methylnicotinate (30 g, 198 mmol) in dry THF (150 mL) was added dropwise into a suspension of LiAlH4 (11 g, 289 mmol) in THF (200 mL) at 0 to −5° C. The grey suspension was stirred at RT for 1 h. The reaction mixture was cooled to −5 to 0° C. and water (11 mL) was added dropwise under nitrogen followed by slow addition of 15% NaOH (11 mL) and water (33 mL). The reaction was warmed to RT and stirred for 30 min. at RT. The resulting suspension was filtered and the filtrate was concentrated under vacuum to give (6-methylpyridin-3-yl)methanol as a yellow oil (23 g).
