Procedure

A dry 25 mL flask was charged with 4-Chloro-2,5-dimethyl-2H-pyrazole-3-carbonyl chloride (0.152 g, 0.794 mmol) and THF (2 mL). 6-(4-Amino-benzoyl)-1,3-dihydro-indol-2-one (as prepared in Example 40, 0.200 g, 0.794 mmol) was added to the THF solution of the acid chloride, and the mixture was allowed to reflux for 4 h. The reaction mixture was then allowed to cool to room temperature. The room temperature reaction mixture was concentrated in vacuo. The tan solids were washed with THF (˜3 mL) and filtered to afford the pure 4-Chloro-2,5-dimethyl-2H-pyrazole-3-carboxylic acid [3-(2-oxo-2,3-dihydro-1H-indole-6-carbonyl)-phenyl]-amide (0.187 g, 0.458 mmol, 58%).
