Versuchsvorschrift

A small screw cap test tube was charged with 3-Methyl-furan-2-carboxylic acid [3-(3-hydroxymethylene-2-oxo-2,3-dihydro-1H-indole-6-carbonyl)-phenyl]-amide (prepared below, 200 mg, 0.515 mmol) and THF (5.0 mL). To the resulting solution was added 4-(2-Pyrrolidin-1-yl-ethyl)-phenylamine (98 mg, 0.515 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 crude residue was purified by flash silica gel chromatography (EtOAc:MeOH mix eluant with gradient of 1% MeOH to 10% MeOH) to afford the title compound in 17% yield (0.049 g, 0.087 mmol).
