Procedure

To a solution of (R)-1-(3-(1-(3-fluoro-5-(1,1,2,2-tetrafluoroethoxy)phenyl)-1-(4-fluorophenyl)-2-phenylethyl)ureido)-cyclopropanecarboxylic acid (84 mg, 0.153 mmol), prepared by the method described in Procedure 30, in DCM (0.5 mL) was added 2-(phenylphosphinylidene)acetonitrile compound with biphenyl (1:1) (51 mg, 0.168 mmol), EDCI (32 mg, 0.168 mmol) and DMAP (3 mg, 0.024 mmol). The reaction mixture was stirred at room temperature for 4.5 h, concentrated under reduced pressure and purified by ISCO chromatography (12 g column, eluting with 0-100% hexane/EtOAc) to yield (R)-1-(1-(2-cyano-2-(phenylphosphinylidene)acetyl)cyclopropyl)-3-(1-(3-fluoro-5-(1,1,2,2-tetrafluoroethoxy)phenyl)-1-(4-fluorophenyl)-2-phenylethyl)urea compound with biphenyl (1:1) as a white solid (53 mg, 42% yield). LCMS: RT=3.49 min [M+H] 836.4 (Phenomenex Luna C18 column, 4.6×50 mm eluting with 50-100% MeOH/H2O over 4 minutes containing 0.1% TFA; 4 mL/min, monitoring at 220 nm); 1H NMR (400 MHz, CDCl3) ppm 0.78-1.00 (m, 2H), 1.34-1.49 (m, 2H), 3.79-3.95 (m, 2H), 5.62-5.98 (m, 3H), 6.67-6.94 (m, 7H), 6.98-7.20 (m, 5H), 7.37-7.66 (m, 15H).
