実験手順

Tert-butyl 4-(aminomethyl)-4-phenylpiperidine-1-carboxylate (355 mg, 1.22 mmol) and 1.15 g PtO2 (5.1 mmol) in 125 ml ethanol were shaked in PARR apparatus under 60 psi of hydrogen for 20 hours. Celite was loaded on top of an ion exchange cartridge (MCX, Phenomenex, 6 g adsorbent). The crude reaction slurry was filtered through this set-up, the pyrophoric catalyst washed with ethanol and water and removed. The cartridge was washed with methanol and then the product eluted with a 2 M solution of NH3 in MeOH. The eluent was concentrated to give 234 mg of the title compound as an oil.
