Versuchsvorschrift

To a 0° C. solution of 2-methoxyisonicotinic acid (M1) (490 mg, 3.20 mmol) in anhydrous THF (15 ml) was added dropwise LAH (3.20 ml, 6.40 mmol) (2.0 N in Et2O), and the mixture was stirred at room temperature for overnight. The reaction mixture was cooled back to 0° C. and 0.28 ml H2O, 0.21 ml of 20% NaOH solution, 0.98 ml H2O were added drop-wise sequentially and stirred for 1 h. The solid was filtered and washed with THF and the filtrate was concentrated to give (2-methoxypyridin-4-yl)methanol (M2) as a clear oil that gave a mass ion (ES+) of 140.1 for M+H+.
