Hydrochloric Acid → (3-Chloro-4-methoxyphenyl)methanol

To a solution of methyl 3-chloro-4-methoxybenzoate (1.2 g, 6 mmol) in tetrahydrofuran (10 ml) was added under ice-cooling lithium aluminum hydride (455 mg, 12 mmol) and the mixture was stirred at room temperature for 1 h. The reaction mixture was stirred under ice-cooling and 0.1N hydrochloric acid was added. The mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure to give an almost pure title compound (1.1 g, 100%).
