5-(2-(4-Pyridinyl)vinyl)-3-(1-BOC-2-(S)-azetidinylmethoxy)pyridine → 5-(2-(4-Pyridinyl)ethyl)-3-(1-BOC-2-(S)-azetidinylmethoxy)pyridine

Participants

Reaction Steps

To a solution of 5-(2-(4-pyridinyl)ethenyl)-3-(1-BOC-2-(S)-azetidinylmethoxy)pyridine from Example 59a (188 mg, 0.51 mmol) in MeOH (10 mL) was added Pd/C (20 mg), and the mixture was stirred at room temperature for 40 hours. The catalyst was filtered off, and the solvent was removed under vacuum. The residue was chromatographed on a silica gel column, eluting with CH2Cl2:MeOH 10:2 to 10:5 to afford the title compound (154 mg). MS (CI/NH3) m/z 370 (M+H)+. 1H NMR (CDCl3, 300 MHz) δ 1.42 (s, 9H), 2.32 (m, 2H), 3.89 (m, 2H), 4.10 (m, 1H), 4.28 (m, 1H), 4.50 (m, 1H), 7.02 (m, 1H), 7.02 (m, 1H), 7.08 (m, 2H), 8.06 (m, 1H), 8.20 (m, 1H), 8.51 (m, 2H).
