Procedure

A solution of trans-N-Boc-2-methyl-6-(2-phenylethenyl)piperidine (3.8, 12.54 mmol) in 6 m/L of ethanol was shaken under 58 psi of H2 pressure over 0.70 g Pd/C catalyst overnight, and then the mixture was filtered through Celite and concentrated to give 3.81 g (quantitative) of the product. No further purification was necessary. 1H NMR (250 MHz) 87.30-7.14 (m, 5H), 3.93-3.89 (m, 2H), 2.64-2.59 (t, 2H), 1.98-1.20 (m, 20H).
