실험 절차

A round bottom flask was charged with IIDQ polystyrene resin (493 mg, 1.5 mmol/g, 0.74 mmol) and acetonitrile (5 mL) and sealed with a rubber septum. The suspension was vacuumed and reflushed with argon three times. To the resulting slurry was added a solution of (R)-1-(4-fluoro-3-isopropoxyphenyl)-1-(3-fluoro-5-(1,1,2,2-tetrafluoroethoxy)phenyl)-2-phenylethanamine, prepared as described in Procedures 109, 110, 111, 112, 113, 114, (180 mg, 0.37 mmol) and 4,4,4-trifluoro-3-(trifluoromethyl)crotonic acid (93 mg, 0.45 mmol) in acetonitrile (5 mL) and the reaction mixture was stirred at room temperature for 18 h. The reaction mixture was filtered and the filtrate was concentrated under reduced pressure and purified by ISCO chromatography (40 g column) using hexane/EtOAc (0-15% over 30 min) to give (R)-4,4,4-trifluoro-N-(1-(4-fluoro-3-isopropoxyphenyl)-1-(3-fluoro-5-(1,1,2,2-tetrafluoroethoxy)phenyl)-2-phenylethyl)-3-(trifluoromethyl)but-2-enamide (Example 291) as a white solid at a retention time of 20 min (199 mg, 74% yield). LCMS: RT=2.18 min [M+H] 674.33 (Phenomenex Luna C18 column, 4.6×30 mm eluting with 10-90% MeOH/H2O over 2 minutes containing 0.1% TFA; 5 mL/min, monitoring at 220 nm); HPLC: RT=4.25 min, Purity 98% (Phenomenex Luna C18 column, 4.6×50 mm eluting with 10-90% MeOH/H2O over 4 minutes containing 0.2% PPA; 4 mL/min, monitoring at 220 nm); NMR: 400 MHz 1H (CDCl3) 7.19 ppm, 3H, m; 7.02 ppm, 1H, dd, J=10.55, 8.79 Hz; 6.95 ppm, 3H, m; 6.85 ppm, 1H, s; 6.67 ppm, 3H, d, J=7.03 Hz; 6.62 ppm, 1H, m; 6.13 ppm, 1H, s; 5.88 ppm, 1H, tt, J=53.00, 2.86, 2.75 Hz; 4.36 ppm, 1H, ddd, J=11.97, 6.15, 6.04 Hz; 3.99 ppm, 1H, d, J=13.18 Hz; 3.71 ppm, 1H, d, J=13.18 Hz; 1.26 ppm, 6H, m.
