1-Phenyl-1H-pyrazole-5-carbonyl chloride → HCID 86610433, compound

Participants

Reaction Steps

A dry flask was charged with 2-Phenyl-2H-pyrazole-3-carbonyl chloride (0.164 g, 0.794 mmol) and THF (8 mL). 6-(3-Amino-benzoyl)-1,3-dihydro-indol-2-one (as prepared in Example 40, 0.200 g, 0.793 mmol) was added to the THF solution of the acid chloride, and the mixture was allowed to reflux overnight. The reaction mixture was then allowed to cool to room temperature and subsequently vacuum filtered. The solid was washed with 0° C. THF (˜5 mL) and collected to afford the 2-Phenyl-2H-pyrazole-3-carboxylic acid [3-(2-oxo-2,3-dihydro-1H-indole-6-carbonyl)-phenyl]-amide as a solid (0.255 g, 0.600 mmol, 76%).
