Procedure

To a solution of the pyrrolidine intermediate from step C (0.3 g, 0.85 mmol) and the ketone from step E (0.16 g, 0.85 mmol) in THF (5 mL) was added Na(OAc)3BH (0.35 g, 2.5 mmol) followed by triethylamine (0.2 mL, 1.5 mmol). The reaction was continued at room temperature overnight and quenched by addition of a saturated NaHCO3 solution. The resulting solution was extracted with EtOAc and the EtOAc layer was dried over MgSO4 and concentrated. Separation on silica gel eluting with 10% to 30% MeOH/EtOAc provided the cis (fast moving spot) and trans (slow moving spot) isomers of the title compound. MS (M+H)+ 490.0.
