Versuchsvorschrift

A solution of methyl 2-methoxy-6-methylnicotinate (5.60 g, 30.9 mmol) in dry tetrahydrofuran (155 mL, 30.9 mmol) under an atmosphere of nitrogen was cooled in an ice bath. Lithium aluminum hydride (1.23 g, 30.9 mmol) was added as a slurry in tetrahydrofuran and the mixture was stirred with cooling in an ice bath for 75 minutes. The reaction mixture was diluted with tetrahydrofuran (30 mL). Some Celite® was added followed by sodium sulfate decahydrate to quench. The mixture was filtered and concentrated under vacuum to give (2-methoxy-6-methylpyridin-3-yl)methanol (4.7 g) which was used without purification.
