Procedure

Into a 50-mL round bottom flask, was placed a solution of tert-butyl 3-(3-((2-(4-((3-(trifluoromethyl)benzyl)carbamoyl)pyridin-2-yl)-4-morpholinophenyl)carbamoyl)benzylthio)propanoate (100 mg, 0.14 mmol, 1.00 equiv) in dichloromethane (5 mL), and trifluoroacetic acid (0.1 mL). The resulting solution was stirred overnight at room temperature. The reaction progress was monitored by LCMS. The resulting mixture was concentrated under vacuum. The crude product (100 mg) was purified by reverse phase HPLC eluting with a water/CH3CN gradient containing 0.05% TFA. The product was obtained as 14 mg (15%) of a yellow solid. 1H-NMR (300 MHz, CDCl3, ppm): δ 13.55 (s, 1H), 9.09 (s, 1H), 8.96-8.78 (m, 2H), 8.72 (s, 1H), 8.65 (s, 1H), 8.25-8.09 (m, 3H), 8.05-7.90 (m, 8H), 4.73 (d, J=5.4 Hz, 2H), 4.13 (s, 4H), 3.82 (s, 2H), 3.47 (s, 4H), 2.75-2.57 (m, 4H). MS (ES, m/z): 679 [M+H]+.
