실험 절차

Trifluoroacetic acid (2.5 mL, 3.7 g, 32 mmol) was added dropwise to a solution of 1-(t-butoxycarbonyl)-4-(3,3-difluoro-3-phenylprop-1-yl)piperidine from Step C (42 mg, 0.12 mmol) in methylene chloride (2.5 mL) at 0° C. After 80 min., the solution was transferred using a double-ended needle to a rapidly stirred solution of sodium bicarbonate (5.0 g, 60 mmol) in water (50 mL). Ether (50 mL) and 2.5 N aq. NaOH (20 mL) were added, followed by solid brine to saturate the aqueous layer. The aqueous layer was separated and extracted with ether (50 mL). The organic layers were washed in succession with saturated aq. brine (20 mL), combined, dried (sodium sulfate), decanted, and evaporated to give the title compound as 27 mg of colorless oil.
