N—((S)-1-(3-(3-chloro-4-cyanophenyl)-1H-pyrazol-1-yl)propan-2-yl)-2-(1-(tetrahydro-2H-pyran-2-yl)-1H-pyrazol-5-yl)oxazole-4-carboxamide (56 mg, 0.111 mmol) was added into a flask under nitrogen atmosphere. 10% HCl/EtOH (0.126 ml, 0.277 mmol) was added and the reaction mixture was stirred in RT for 2 h. The reaction mixture was diluted with ethyl acetate and washed with 1M Na2CO3. The organic phase was dried, filtered and evaporated. The product was triturated using acetonitrile and THF, respectively. Yield 29.6%. 1H-NMR (400 MHz; CDCl3): δ 1.27 (d, 3H), 4.31 (dd, 1H), 4.43 (dd, 1H), 4.61 (m, 1H), 6.61 (d, 1H), 6.86 (d, 1H), 7.49 (d, 1H), 7.60 (d, 1H), 7.66 (d, 1H), 7.72 (d, 1H), 7.87 (dd, 1H), 7.92 (d, 1H), 8.23 (s, 1H), 10.78 (s, 1H).
