Reaction Steps

In a 75-mL Parr bottle, 1-(4-nitrophenyl)piperidine-4-carboxylic acid (0.13 g, 0.52 mmol) is dissolved in ethanol/ethyl acetate (1:1, 30 mL). Concentrated hydrochloric acid (0.5 mL) is added. After degassing the mixture with dry ice, palladium on carbon (10%, 30 mg) is added. The reaction mixture is shaken overnight under 50 psi hydrogen, then filtered through a pad of diatomaceous earth and concentrated under reduced pressure to give 1-(4-aminophenyl)piperidine-4-carboxylic acid dihydrochloride.
