Participants

Reaction Steps

A mixture of (S)—N-(1-(3-(3-chloro-4-cyano-5-fluorophenyl)-1H-pyrazol-1-yl)propan-2-yl)-5-(2-hydroxypropan-2-yl)isoxazole-3-carboxamide (50 mg, 0.116 mmol), 5 ml of dry methanol and cesium carbonate (75 mg, 0.232 mmol) was reacted with stirring for 6 days keeping the temperature at 60° C. during the day and at RT during the night. The mixture was evaporated dissolved in DCM, extracted with water and dried. The product was purified by flash chromatography. Yield 60.3%. 1H-NMR (400 MHz; DMSO-d6): δ 1.15 (d, 3H), 1.46 (s, 6H), 4.01 (s, 3H), 4.32 (d, 2H), 4.40-4.51 (m, 1H), 5.68 (s, 1H), 6.49 (s, 1H), 7.00 (d, 1H), 7.54 (d, 1H), 7.67 (d, 1H), 7.83 (d, 1H), 8.75 (d, 1H).
