To a solution Intermediate 14D (558 mg, 1.140 mmol) in pyridine (5.7 mL) was added lithium iodide (1.53 g, 11.4 mmol). The reaction was heated to reflux overnight. The reaction was cooled to rt and diluted with water and EtOAc. The aqueous layer was made acidic with 1 N HCl and the layers were separated. The organic layer was washed with sat'd aq NaCl, dried over MgSO4, filtered and concentrated to provide Intermediate 14E (506 mg, 84%) which was used in the next step without further purification. LCMS Anal. Calc'd for C23H23F6NO3 475.42, found [M+H] 476.2.
