Procedure

TFA (1 ml) was added to a solution of 1,1-dimethylethyl[(2S)-2-({[4-(1-methyl-1H-1,2,4-triazol-5-yl)-2-thienyl]carbonyl}amino)-3-phenylpropyl]carbamate (100 mg, 0.226 mmol) in DCM (5 ml). The reaction was stirred at RT for 30 min. The solvent was removed and the residue was purified by reverse phase HPLC (10% org˜60% org) to give the title compound as a white solid (90 mg, 87%). LC-MS (ES) m/z 342.2 (M+H)+, 1H NMR (d4-MeOH, 400 MHz) δ 8.23 (s, 1H), 8.03 (m, 2H), 7.22-7.31 (m, 5H), 4.60 (m, 1H), 4.08 (s, 3H), 3.10-3.20 (m, 2H), 3.00 (m, 2H).
