Procedure
Add Pd/C (10%, 70 mg) to the solution of 4-fluoro-1-(3-nitro-5-(trifluoromethyl)phenyl)piperidine (300 mg, 1.0 mmol) in methanol (10 mL), stir the mixture under hydrogen atmosphere for 16 hrs at room temperature. Filter and concentrate the filtrate to get the crude product (270 mg, 100%) which is used directly without further purification.
