Add 3.2 g (0.085 mole) cyclopropyl-4-fluorobenzylmethanone to 80 ml of 3.2 g (0.085 mole) sodium borohydride partially dissolved in absolute ethanol, following the reaction by thin-layer chromatography. After about 6 hours at room temperature, cool the reaction in an ice bath and add acetic acid. Extract the mixture with methylene (3×60 ml) wash the methylene chloride extracts with saturated aqueous sodium bicarbonate solution, and dry over magnesium sulfate. Evaporate the methylene chloride extracts and dry in vacuo to yield the title compound.
