Procedure

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).
