Reaction Steps

1,1-Dimethylethyl[2-(hydroxy{[4-(1-methyl-1H-pyrazol-5-yl)-2-thienyl]carbonyl}amino)-3-phenylpropyl]carbamate (84 mg, 0.19 mmol) was dissolved in DCM (2 mL) and treated with TFA (1 mL). The reaction was stirred over 1 h, and concentrated, and purified by reverse-phase HPLC (C18 column: H2O/CH3CN, 40-10%), and concentrated to afford the bis-TFA salt of the title compound (51.2 mg, 64.8%). LC-MS (ES) m/z 357 (M+H)+, 1H NMR (d4-MeOD, 400 MHz) δ ppm 8.03 (s, 1H), 7.94 (d, J=1.8 Hz, 1H), 7.52 (d, J=1.8 Hz, 1H), 6.46 (d, J=1.8 Hz, 1H), 7.34-7.18 (m, 5H), 5.16 (m, 1H), 3.95 (s, 3H), 3.38 (dd, J=13.1, 10.6 Hz, 1H), 3.17-3.11 (m, 2H), and 2.95 (dd, J=13.6, 6.6 Hz, 1H)
