Versuchsvorschrift

LiBH4 (5.10 g, 0.23 mmol) was added to a solution of 2-methoxy-3-methyl-benzoic acid methyl ester (8.46 g, 47.00 mmol) in Et2O at 0° C. The reaction mixture was stirred for 5 minutes, MeOH (9.50 mL, 0.23 mmol) was added in a dropwise fashion. The reaction mixture was then stirred for 30 minutes, and was quenched into 1N NaOH. The resulting solution was extracted with Et2O (3×200 mL) and the combined organic phases were washed with brine (1×150 mL), dried over MgSO4 and concentrated to afford the title compound.
