A small screw cap test tube was charged with 2,5-Dimethyl-2H-pyrazole-3-carboxylic acid [3-(3-hydroxymethylene-2-oxo-2,3-dihydro-1H-indole-6-carbonyl)-phenyl]-amide (as prepared in Example 60, 116 mg, 0.288 mmol) and THF (2 mL). To the resulting solution was added N-(2-Dimethylamino-1-methyl-ethyl)-benzene-1,4-diamine (prepared below, 61.4 mg, 0.314 mmol), and the mixture was stirred for 24 h at 65° C. Subsequently, the reaction mixture was cooled to room temperature. Hexanes were added to the reaction mixture and the reaction mixture was vacuum filtered. The black solid collected was set aside. The filtrate was then concentrated in vacuo and then redissolved into EtOAc and then Hexanes were added causing a precipitate to form. The precipitate was then filtered and washed with ˜1 mL of i-prOH yielding 40% (0.067 g, 0.116 mmol) of the title compound.
