4-(3-Fluoro-phenyl)-4-oxo-butyronitrile (1.60 g, 9.03 mmol) dissolved in MeOH (45 ml) and 3.5 N MeOH-NH3 (45 ml) was hydrogenated on Ra-Ni at RT for 16 h. The catalyst was filtered off, the filtrate evaporated and the crude product purified by column chromatography on silica gel (ethyl acetate/toluene 1:2) to give the product (1.16 g, 79%) as a colorless oil, MS: m/e=163 (M+).
