To a solution of (R)-1-(3-fluoro-5-(1,1,2,2-tetrafluoroethoxy)phenyl)-1-(4-fluorophenyl)-2-phenylethanamine (30 mg, 0.079 mmol) in CH2Cl2 (0.2 mL) was added 4-fluoro-3-(trifluoromethyl)benzoyl chloride (0.048 mL, 0.158 mmol), followed by Et3N (0.04 mL, 0.158 mmol). The resulting mixture was stirred at room temperature for 5 h. The crude product was purified on a preparative HPLC column type using 30 to 100% CH3CN in H2O with 0.1% TFA for 10 minutes as mobile phase. The solvent was removed under reduced pressure to afford (R)-4-fluoro-N-(1-(3-fluoro-5-(1,1,2,2-tetrafluoroethoxy)phenyl)-1-(4-fluorophenyl)-2-phenylethyl)-3-(trifluoromethyl)benzamide (35 mg, 80% yield) as white powder. LC-MS (ESI) 568.30 (M+H), retention time=4.27 min (0-100% MeOH in H2O with 0.1% TFA in a 4-min run); Analytical HPLC: 3.95 min (0-100% CH3CN in H2O with 0.1% TFA in a 4-min run, purity 100%); 1H NMR (400 MHz, CD3OD) δ ppm 3.88-4.01 (m, 1H), 4.10 (d, J=13.18 Hz, 1H), 6.69 (d, J=7.47 Hz, 2H), 6.97-7.51 (m, 11H), 7.99 (d, J=5.71 Hz, 2H), 8.90 (s, 1H).
