Reaction Steps

To a solution of 3-(1,3-dioxoisoindolin-2-yl)-4,4,4-trifluoro-N—((R)-1-(3-fluoro-5-(1,1,2,2-tetrafluoroethoxy)phenyl)-1-(4-fluorophenyl)-2-phenylethyl)butanamide (Example 325, 30 mg, 0.04 mmol) in MeOH (1 mL) was added hydrazine (0.03 mL, 1 mmol) and the reaction mixture was heated at 50° C. for 4 h. The reaction mixture was purified by preparative HPLC (Axia luna column, 30×75 mm, 10-100% ACN/H2O with 0.1% TFA over 10 min, flow rate 40 mL/min, monitoring at 220 nm) to yield 3-amino-4,4,4-trifluoro-N—((R)-1-(3-fluoro-5-(1,1,2,2-tetrafluoroethoxy)phenyl)-1-(4-fluorophenyl)-2-phenylethyl)butanamide (Example 326) as white solid (7 mg, 24% yield). LCMS: RT=3.62 min [M+H] 565.2 (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) δ ppm 7.34 (1H, d, J=17.94 Hz), 7.13-7.24 (3H, m), 6.96-7.11 (4 H, m), 6.82-6.92 (3H, m), 6.62 (2H, d, J=7.83 Hz), 5.86 (1H, t, J=1.77 Hz), 3.88 (1H, t, J=12.63 Hz), 3.75-3.84 (1H, m), 3.70 (1H, d, J=13.14 Hz), 2.82-2.93 (1H, m), 2.77 (1H, m).
