Reaction Steps

A solution of (R)—N-(1-(4-fluoro-3-hydroxyphenyl)-1-(3-fluoro-5-(trifluoromethyl)phenyl)-2-phenylethyl)-3-(trifluoromethyl)benzamide, prepared as described in Example 264, (15 mg, 0.027 mmol), methylisocyanate (0.01 mL), and Et3N (0.02 mL) in CH2Cl2 (0.3 mL) was heated at 80° C. under microwave irradiation for 10 min. After cooling, the reaction mixture was diluted with EtOAc and the organic layer was washed with H2O, sat. NaCl, dried over Na2SO4, filtered and concentrated. The residue was purified by ISCO flash chromatography (silica gel, hexanes/EtOAc) to yield (R)-2-fluoro-5-(1-(3-fluoro-5-(trifluoromethyl)phenyl)-2-phenyl-1-(3-(trifluoromethyl)-benzamido)-ethyl)phenyl methylcarbamate (Example 272, 11 mg, yield: 61%). LCMS: RT=2.13 min [M+H] 623.3 (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).
