Reaction Steps

Sodium borohydride (86 mg, 2.262 mmol) was added into a flask and the atmosphere was replaced with nitrogen. Dry ethanol was added and the reaction mixture was cooled to 0° C. (S)-ethyl 4-(1-(3-(3-chloro-4-cyanophenyl)-1H-pyrazol-1-yl)propan-2-ylcarbamoyl)thiazole-2-carboxylate (502 mg, 1.131 mmol) was added and the reaction mixture was warmed slowly to RT while stirring overnight. The crude product was cooled to 0° C., water was added dropwise, the pH was adjusted to 7 and the mixture was evaporated. DCM and a few drops of methanol were added and the crude product was washed with 1M Na2CO3 and with water. Yield 58.6%. 1H-NMR (400 MHz; DMSO-d6): δ 1.12 (d, 3H), 4.31 (dd, 1H), 4.40 (dd, 1H), 4.43-4.51 (m, 1H), 4.79 (d, 2H), 6.20 (t, 1H), 6.95 (d, 1H), 7.84 (d, 1H), 7.96 (dd, 1H), 7.98 (dd, 1H), 8.08 (dd, 1H), 8.13 (s, 1H), 8.50 (d, 1H).
