To a solution of (R)-1-(1-(bromomethyl)cyclopropyl)-3-(1-(3-fluoro-5-(1,1,2,2-tetrafluoroethoxy)phenyl)-1-(4-fluorophenyl)-2-phenylethyl)urea (8 mg, 0.013 mmol) in DMSO (0.3 mL) was added NaCN (18 mg, 0.37 mmol) and KI (20 mg, 0.12 mmol). The reaction mixture was stirred at rt for 3 days. The reaction mixture was concentrated under reduced pressure and purified by preparative HPLC (Phenomenex AXIA Luna column, 30×100 mm, flow rate 40 mL/min, 30-100% ACN/H2O/0.1% TFA over 12 min) to yield (R)-1-(1-(cyanomethyl)cyclopropyl)-3-(1-(3-fluoro-5-(1,1,2,2-tetrafluoroethoxy)phenyl)-1-(4-fluorophenyl)-2-phenylethyl)urea (Example 242, 5 mg, 63% yield). LCMS: RT=3.88 min [M+H] 548.3 (Phenomenex Luna C18 column, 4.6×50 mm eluting with 10-90% MeOH/H2O over 4 minutes containing 0.1% TFA; 4 mL/min, monitoring at 220 nm); 1H NMR (400 MHz, CDCl3) ppm 0.76-0.91 (m, 4H), 2.58 (qt, J=17 Hz, 2H), 3.78 (qt, J=12 Hz, 2H), 5.49 (s, 1H), 5.52 (s, 1H), 5.87 (t, J=53 Hz, 1H), 6.66 (d, J=6.6 Hz, 2H), 6.84-6.95 (m, 3H), 6.96-7.07 (m, 2H), 7.07-7.26 (m, 5H).
