The title compound was prepared by a method analogous to the one used for Intermediate 1, but using 3,3-difluoropyrrolidine instead of pyrrolidine for Step 1 and a solution of hydrogen chloride in methanol (1.25 M) for Step 2. MS (ES+) (M+H) 326.1; LCMS retention time: 0.26 minutes (Method M). 1H NMR (DMSO, 400 MHz): δ 1.45-1.62 (m, 2H), 1.65-1.72 (m, 1H), 1.82-1.90 (m, 1H), 2.30-2.45 (m, 2H), 2.76-2.91 (m, 2H), 3.46-3.54 (m, 1H), 3.64-3.78 (m, 2H), 3.84-3.92 (m, 1H), 3.95-4.04 (m, 2H), 4.06-4.13 (m, 1H), 4.13-4.62 (m, 6H), 6.14 (d, 1H), 7.24 (d, 1H).
