Reaction Steps

A small screw cap test tube was charged with 5-Chloro-1-methyl-1H-pyrazole-4-carboxylic acid [3-(3-hydroxymethylene-2-oxo-2,3-dihydro-1H-indole-6-carbonyl)-phenyl]-amide (as prepared in Example 328, 100 mg, 0.2365 mmol) and THF (2.5 mL). To the resulting solution was added 4-(2-Pyrrolidin-1-yl-ethyl)-phenylamine (45 mg, 0.236 mmol), and the mixture was stirred for 24 h at 65° C. Subsequently, the reaction mixture was cooled to room temperature and diluted with EtOAc (˜5 mL) and Hexane (˜50 mL). The precipitate that formed was collected by filtration and washed with acetone (˜15 mL) to afford the title compound in 29% yield (0.041 g, 0.0689 mmol).
