Reaction Steps

A small screw cap test tube was charged with 1,5-Dimethyl-1H-pyrazole-4-carboxylic acid [3-(3-hydroxymethylene-2-oxo-2,3-dihydro-1H-indole-6-carbonyl)-phenyl]-amide (prepared below, 134 mg, 0.333 mmol) and THF (3.3 mL). To the resulting solution was added 4-(4-methyl-piperazin-1-yl)-phenylamine (64.2 mg, 0.336 mmol), and the mixture was stirred for 24 h at 65° C. Subsequently, the reaction mixture was cooled to room temperature and concentrated in vacuo. The residue was dissolved in EtOAc (˜5 mL) and the resulting solution was triturated with Hexanes (˜40 mL). The precipitate that formed was collected by filtration and washed with 0° C. iPrOH (˜10 mL) to afford the title compound in 11% yield (0.021 g, 0.036 mmol).
