Versuchsvorschrift

To a solution of aluminum lithium hydride (1.43 g) in THF (126 ml) was added a solution of methyl 2-methoxynicotinate (6.3 g) in THF (63 ml) at 0° C. The mixture was stirred at room temperature for 2 hours, and water (6.3 ml), 15% aqueous solution of sodium hydroxide (6.3 ml) and water (18.9 ml) were sequentially added to the solution at 0° C. The mixture was filtered with Celite, and washed with methanol. The solvent was removed under reduced pressure, and the obtained residue was purified by silica gel column chromatography, to give (2-methoxy-3-pyridinyl)methanol (5.0 g).
