실험 절차
7a-(3-Benzyloxy-5-pyridinyl)-hexahydro-1H-pyrrolizine (260 mg, 0.88 mmol, from step 16b) was dissolved in methanol (9 mL), 10% Pt/C (35 mg) was added, and the mixture stirred under 1 arm of H2 for 16 hours. The catalyst was removed, the filtrate was concentrated, and the residue was chromatographed (silica gel; CHCl3 /MeOH/0.5 % NH4OH, 90:10:0 to 90:10:0.5) to afford the title compound as a white solid (114 mg, 63%). 1H NMR D2O, 300 MHz) δ2.07-2.40 (m, 6H), 2.49-2.58 (m, 2H), 3.26-3.34 (m, 2H), 3.71-3.80 (m, 2H), 7.00 (dd, J=2.4, 2.0 Hz, 1H), 7.80 (d, J=2.0 Hz, 1H), 7.85 (d, J=2.4 Hz, 1H): MS (CI/NH3) m/z: 205 (M+H)+.
