Procedure
A mixture of 1-(4-fluorophenyl)-4-(4-nitrophenyl)butan-1-one (0.5 g, 1.7 mmol) and 10% palladium on carbon (0.06 g) in ethyl acetate (15 mL) and tetrahydrofuran (5 mL) was hydrogenated at room temperature using the hydrogen balloon. The catalyst was removed by filtration, and the filtrate concentrated in vacuo. Purification by silica gel chromatography, eluting with 10% ethyl acetate/hexane gave the title compound as a white solid (0.34 g, 78%). The product was used in the next step.
