Reaction Steps

N—((S)-1-(3-(3-chloro-4-cyanophenyl)-1H-pyrazol-1-yl)propan-2-yl)-5-(1-hydroxyethyl)isoxazole-3-carboxamide (28 mg, 0.070 mmol) and DMAP (0.864 mg, 7.00 μmmol) were dissolved in pyridine under nitrogen atmosphere. The reaction mixture was cooled to 0° C., acetic anhydride (7.51 mg, 0.074 mmol) was added and the reaction mixture stirred for 2 h. The solvent was evaporated. Yield 82%. 1H-NMR (400 MHz; CDCl3): δ 1.23 (d, 3H), δ 1.64 (d, 3H), 2.11 (s, 3H), 4.25 (dd, 1H), 4.43 (dd, 1H), 4.54-4.63 (m, 1H), 6.05 (q, 1H), 6.63 (d, 1H), 6.65 (d, 1H), 7.48 (d, 1H), 7.70 (d, 1H), 7.84 (dd, 1H), 7.89 (d, 1H), 8.06 (d, 1H).
