Vorschrift

A small screw cap test tube was charged with 2-Ethyl-5-methyl-2H-pyrazole-3-carboxylic acid [3-(3-hydroxymethylene-2-oxo-2,3-dihydro-1H-indole-5-carbonyl)-phenyl]-amide (as prepared in Example 1, 30 mg, 0.072 mmol) and THF (1 mL). To the resulting solution was added 4-(4-methyl-piperazin-1-yl)-phenylamine (20.7 mg, 0.1082 mmol), and the mixture was stirred for 24 h at 65° C. Subsequently, the reaction mixture was cooled to room temperature. The reaction mixture was concentrated in vacuo and purified via flash silica gel chromatography (5% MeOH/95% CHCl3) providing the title compound in 57% yield (24 mg, 0.0407 mmol).
