Procedure

A dry flask was charged with 5-tert-Butyl-2-methyl-2H-pyrazole-3-carbonyl chloride (0.207 g, 1.03 mmol) and THF (10 mL). 6-(3-Amino-benzoyl)-1,3-dihydro-indol-2-one (as prepared in Example 40, 0.260 g, 1.03 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 5-tert-Butyl-2-methyl-2H-pyrazole-3-carboxylic acid [3-(2-oxo-2,3-dihydro-1H-indole-6-carbonyl)-phenyl]-amide as a solid (0.390 g, 0.94 mmol, 91%).
