Versuchsvorschrift

A small screw cap test tube was charged with 5-Ethyl-1-methyl-1H-pyrazole-3-carboxylic acid [3-(3-hydroxymethylene-2-oxo-2,3-dihydro-1H-indole-6-carbonyl)-phenyl]-amide (prepared below, 61 mg, 0.1465 mmol) and THF (2.0 mL). To the resulting solution was added 4-(4-methyl-piperazin-1-yl)-phenylamine (27.7 mg, 0.145 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 solid residue was recrystallized with 5 mL of i-prOH affording the title compound in 12% yield (0.010 g, 0.017 mmol).
