Reaction Steps

The above benzonitrile (100 mg, 0.427 mmol) was dissolved in 1:1 ethyl acetate/methanol (10 mL) in a nitrogen-flushed flask. Ammonium formate (270 mg, 4.27 mmol) and palladium on carbon (30 mg, 10% wet) were added and the mixture was heated to reflux for 30 min. The reaction was cooled to room temperature and filtered through a pad of diatomaceous earth, eluting with ethyl acetate. The ethyl acetate was evaporated under vacuum. The resulting residue was purified by chromatography on silica gel (1:1 ethyl acetate/hexanes) to afford the title compound, (67 mg, 77%) as a colorless oil.
