To a suspension of LiAlH4 (4.5 mmol; 0.172 g) in anhydrous THF (5.0 ml) cooled to 0° C. was added dropwise a solution of methyl 4-(2-bromoethyl)benzenecarboxylate (1.0 g; 4.1 mmol) in anhydrous THF (10.0 ml). The reaction mixture was stirred for 5 minutes at room temperature and, after adding ice, was filtered through a Büchner filter. The solvent was removed under reduced pressure and the residue was extracted with ethyl acetate (3×100 ml). The combined organic phases were washed with saturated NaCl solution, dried over sodium sulfate and evaporated under reduced pressure. 800 mg (82.6%) of pure product were thus obtained as an oil.
