Reaction Steps

Into a 100-mL round-bottom flask, was placed a solution of tert-butyl 3-(3-(2-(6-(3-methylbenzylamino)pyrimidin-4-yl)-4-(piperidin-1-yl)phenylcarbamoyl)benzylthio)propanoate (180 mg, 0.28 mmol, 1.00 equiv) in dichloromethane (5 mL), and 2,2,2-trifluoroacetic acid (2 mL). The resulting solution was stirred for 3 h at room temperature. The resulting mixture was concentrated under vacuum. The crude product was purified by reverse phase HPLC eluting with a water/CH3CN gradient containing 0.05% TFA. The product was obtained as 84 mg (51%) of a yellow solid. 1H-NMR (300 MHz, DMSO-d6, ppm): δ 9.42 (s, 1H), 8.84 (s, 1H), 7.80 (s, 1H), 7.71 (m, 2H), 7.52 (m, 1H), 7.45 (m, 1H), 7.24 (m, 6H), 6.90 (s, 1H), 5.42 (s, 2H), 4.64 (m, 1H), 3.82 (s, 2H), 3.26 (m, 4H), 2.59 (m, 2H), 1.67 (m, 6H). MS (ES, m/z): 596 [M+H]+.
