N—((S)-1-(3-(3-chloro-4-cyanophenyl)-1H-pyrazol-1-yl)propan-2-yl)-5-(2-(tetrahydro-2H-pyran-2-yloxy)propyl)isoxazole-3-carboxamide (0.1 g, 0.201 mmol), ethanol (2 ml) and hydrogen chloride, 10% in EtOH (0.5 ml, 1.350 mmol) were mixed together and stirred over the weekend at RT. The mixture was evaporated, more ethanol was added and evaporated again. The product was pure enough without further purifications. Yield 51.7%. 1H-NMR (400 MHz; DMSO-d6): δ 1.09 (dd, 3H), 1.15 (d, 3H), 2.82-2.86 (m, 2H), 3.91-3.98 (m, 1H), 4.29-4.34 (m, 2H), 4.41-4.50 (m, 1H), 6.48-6.50 (m, 1H), 6.94 (d, 1H), 7.82 (d, 1H), 7.92 (dd, 1H), 7.97 (d, 1H), 8.08-8.10 (m, 1H), 8.73 (d, 1H).
