Reaction Steps

A small screw cap test tube was charged with 5-tert-Butyl-2-methyl-2H-pyrazole-3-carboxylic acid [3-(3-hydroxymethylene-2-oxo-2,3-dihydro-1H-indole-6-carbonyl)-phenyl]-amide (prepared below, 128 mg, 0.288 mmol) and THF (3.0 mL). To the resulting solution was added 4-(4-methyl-piperazin-1-yl)-phenylamine (54.8 mg, 0.286 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 (˜40 mL). The precipitate that formed was collected by filtration and washed with 0° C. iPrOH (˜10 mL) to afford the title compound in 29% yield (0.051 g, 0.083 mmol).
