Procedure

1-(t-Butoxycarbonyl)-4-(3,3-difluoro-3-(4-fluorophenyl)prop-1-yl)piperidine from Step G (122 mg, 0.34 mmol) was dried by evaporation of a toluene solution at reduced pressure. The residue was dissolved in chloroform (7.6 mL) and iodotrimethylsilane (0.100 mL, 141 mg, 0.70 mmol) was added. After stirring 30 min at rt, the solution was poured into a mixture of saturated aqueous sodium bicarbonate (15 mL) and 2.5 N aq. NaOH (5 mL), and extracted with ether (50 mL). The organic layer was washed with saturated aq. brine (15 mL), dried (sodium sulfate), decanted, and evaporated to give the title compound as 88 mg of colorless oil.
