Reaction Steps

(S)-tert-butyl 4-(4-(1-(3-(3-chloro-4-cyanophenyl)-1H-pyrazol-1-yl)propan-2-ylcarbamoyl)thiazol-2-yl)piperidine-1-carboxylate (0.3 g, 0.540 mmol) and TFA (0.768 g, 6.73 mmol) was dissolved in a mixture of DCM/TFA/H2O and stirred overnight. The reaction mixture was diluted with DCM, washed with saturated Na2CO3 and with water. The organic layer was evaporated. Yield 82%. 1H-NMR (400 MHz; DMSO-d6): δ 1.24 (d, 3H), 1.52 (dd, 1H), 1.58 (dd, 1H), 1.91-1.97 (m, 2H), 2.54-2.62 (m, 2H), 2.97-3.03 (d, 2H), 3.04-3.11 (m, 1H), 4.33 (dd, 1H), 4.41 (dd, 1H), 4.44-4.51 (m, 1H), 6.96 (d, 1H), 7.85 (d, 1H), 7.94 (dd, 1H), 7.99 (d, 1H), 8.07 (d, 1H), 8.08 (s, 1H), 8.28 (d, 1H).
