A dry flask was charged with 5-Chloro-1-methyl-1H-pyrazole-4-carbonyl chloride (0.200 g, 1.1 mmol) was dissolved in THF (10 mL). 6-(3-Amino-benzoyl)-1,3-dihydro-indol-2-one (as prepared in Example 40, 0.178 g, 0.706 mmol) was added to the THF solution of the acid chloride, and the mixture was allowed to reflux for overnight. The reaction mixture was then allowed to cool to room temperature. The room temperature reaction mixture was filtered. The solid residue was washed with 0° C. THF (10 mL) to afford the 5-Chloro-1-methyl-1H-pyrazole-4-carboxylic acid [3-(2-oxo-2,3-dihydro-1H-indole-6-carbonyl)-phenyl]-amide as a solid (0.199 g, 0.504 mmol, 71%).
