Reaction Steps

To a solution of benzyl 1,1,1-trifluoro-3-((R)-1-(3-fluoro-5-(1,1,2,2-tetrafluoroethoxy)phenyl)-1-(4-fluorophenyl)-2-phenylethylamino)-3-oxopropan-2-ylcarbamate (10 mg, 0.014 mmol) in CH2Cl2 (0.5 m) was added TMSI (18 mg, 0.094 mmol). The reaction mixture was sealed and stirred at rt for 20 h. The reaction mixture was concentrated under reduced pressure and the residue was purified by prep HPLC (Phenomenex Luna AXIA 5μ 21.2×100 mm, 10%-90% ACN/H2O containing 0.1% TFA, flow rate 20 mL/min, gradient time 10 min) to yield 2-amino-3,3,3-trifluoro-N—((R)-1-(3-fluoro-5-(1,1,2,2-tetrafluoroethoxy)phenyl)-1-(4-fluorophenyl)-2-phenylethyl)propanamide (Example 324) as a white solid (5 mg, 65% yield). HPLC: RT=1.90 min [M+H] 551.5 (Phenomenex Luna C18 column, 4.6×50 mm eluting with 10-90% MeOH/H2O over 2 minutes containing 0.1% TFA; 5 mL/min, monitoring at 220 nm); 1H NMR (400 MHz, CDCl3) δ ppm 7.82-7.85, m, 1H, 7.19-7.23, m, 1H, 7.11-7.17, m, 2H, 7.07-7.11, m, 1H, 6.98-7.03, m, 3H, 6.89-6.93, m, 2H, 6.80-6.86, m, 1H, 6.61-6.64, m, 2H, 5.73-5.99, t, J=52, 1H, 4.00-4.03, J=12, d, 1H, 3.98, m, 1H, 3.63-3.67, d, J=12, 1H;
