Versuchsvorschrift

To a solution of aluminum lithium hydride (2.0 g) in THF (160 ml) was added dropwise a solution of methyl 2-methylnicotinate (8.0 g) in THF (80 ml) at 0° C. The mixture was stirred for 2 hours at room temperature, and water (8.0 ml), 15% aqueous solution of sodium hydroxide (8.0 ml) and water (24.0 ml) were sequentially added to the mixture 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-methyl-3-pyridinyl)methanol (4.6 g).
