Reaction Steps

A small screw cap test tube was charged with 5-Chloro-1,3-dimethyl-1H-pyrazole-4-carboxylic acid [3-(3-hydroxymethylene-2-oxo-2,3-dihydro-1H-indole-6-carbonyl)-phenyl]-amide (prepared below, 100 mg, 0.244 mmol) and THF (2 mL). To the resulting solution was added 4-(4-Methyl-piperazin-1-yl)-phenylamine (46.7 mg, 0.244 mmol), and the mixture was stirred for 24 h at 65° C. The reaction mixture was cooled to room temperature and concentrated in vacuo. The crude mixture was redissolved into ˜2 mL of EtOAc and then Hexanes were added to causing a precipitate to form. The precipitate was then filtered yielding 45% (0.067 g, 0.109 mmol) of the title compound.
