実験手順

To a solution of 1-isocyanato-2-phenoxybenzene (29.14 mg, 0.138 mmol) in DMF (0.5 mL) was added a solution of 2-(3-pyridin-3-yl-4,5-dihydro-1H-pyrazol-5-yl)phenol (29.9 mg, 0.125 mmol) in DMF (0.5 mL) and DCE (0.5 mL) at rt. The reaction mixture was shaken at rt for 20 h. The reaction mixture was diluted with a saturated solution of sodium bicarbonate (2 mL) and extracted with DCM. The organic solutions were combined, dried over MgSO4, filtered, and concentrated. The residue was purified by RP-HPLC to give 5-(2-hydroxyphenyl)-N-(2-phenoxyphenyl)-3-pyridin-3-yl-4,5-dihydro-1H-pyrazole-1-carboxamide (I-85) (7.24 mg, 12.8%). LCMS: (FA) ES+ 451.3.
