To a solution of tert-butyl 3-((3-((4-(piperidin-1-yl)-2-(6-((3-(trifluoromethyl)benzyl)amino)pyrimidin-4-yl)phenyl)carbamoyl)benzyl)thio)propanoate in 1 mL of dichloroethane was added 1 mL of TFA. The mixture was stirred 1 h, and then the solvent was evaporated. The residue was purified by chromatography on silica gel to give 100 mg of a yellow solid. 1H NMR (400 MHz, DMSO-d6) δ 8.82 (s, 1H), 7.82 (s, 1H), 7.78-7.60 (m, 4H), 7.59-7.50 (m, 4H), 7.45 (t, J=7.6 Hz, 1H), 7.34-7.15 (m, 2H), 6.97 (s, 1H), 4.76 (s, 2H), 3.84 (s, 2H), 3.26 (s, 4H), 2.64-2.54 (m, 2H), 2.53-2.45 (m, 2H), 1.73-1.62 (m, 4H), 1.62-1.50 (m, 2H). MS (ES, m/z): 650.28 [M+H]+.
