실험 절차
A solution of (E)-tert-butyl 4-{(ethoxycarbonyl)methylene}-3,3-dimethylpiperidine-1-carboxylate (784 mg, 2.64 mmol) in MeOH (10 mL) containing Pd/C (131 mg) was hydrogenated at 1 atm. After 10 h, the mixture was filtered, and the filter cake was washed with MeOH. The combined filtrates were concentrated to afford the titled compound (540 mg, 68%): 1H NMR (CDCl3) δ 4.13 (q, J=6.8 Hz, 2H), 4.05 (m, 1H), 3.57 (m, 1H), 2.57 (m, 1H), 2.46 (dd, J=15.2, 3.2 Hz, 1H), 1.93 (dd, J=15.2, 10.4 Hz, 1H), 1.76 (m, 1H), 1.59-1.50 (m, 2H), 1.45 (s, 9H) 1.34 (m, 1H), 1.26 (t, J=6.8 Hz, 3H), 0.91 (s, 3H), 0.79 (s, 3H).
