実験手順
Pd/C (378 mg) was added to a stirred solution of 1-(3-phenyl-propyl)-piperidine-4-carboxylic acid benzyl ester (1.89 g, 5 mmol) in MeOH (38 mL) and stirring was continued under hydrogen atmosphere for 2 hrs. The mixture was filtered over a bed of celite. The celite was washed with MeOH and the filtrate was concentrated under reduced pressure to afford 1.502 mg (93.93% yield) of 1-(3-phenyl-propyl)-piperidine-4-carboxylic acid. LCMS Purity: 95.08%.
