実験手順
2-(3-Trifluoromethyl-phenyl)-cyclopropanecarboxylic acid ethyl ester (prepared as per literature procedure) (0.70 g, 2.7 mmol) in THF (5 ml) was added to a solution of lithium aluminium hydride (0.123 g, 3.25 mmol) in THF (5 ml) at 0° C. over a period of 10 min. and stirred further at 20-25° C. for 2 hours. The reaction mixture was diluted with THF (15 ml) and quenched with 10% NaOH solution (5 ml) and water (10 ml). The aqueous layer was extracted with ethyl acetate, washed with saturated brine solution and dried over Na2SO4. The organic layer was evaporated to afford [2-(3-trifluoromethyl-phenyl)-cyclopropyl]-methanol as a colorless oil (0.54 g, 92%).
