Procedure
590 mg (15.4 mmol) of LiAlH4 were added in portions at 0° C. to a solution of 2.2 g (10.3 mmol) of 4-(3-(trifluoromethyl)phenyl)but-3-en-2-one in THF (20 ml), and stirring was then carried out for 1 h at RT. The mixture was then quenched at 0° C. with a sat. aq. Na2SO4 sol. and the reaction solution was filtered over kieselguhr. The filtrate was extracted with EA (3×60 ml) and the combined organic phases were washed with water, dried over Na2SO4, filtered and concentrated in vacuo. There were obtained as residue 2.0 g (9.2 mmol, 89%) of 4-(3-(trifluoromethyl)phenyl)-butan -2-ol, which was reacted further without additional purification.
