Reaktionsschritte

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 (as prepared in Example 354, 100 mg, 0.2575 mmol) and THF (2.6 mL). To the resulting solution was added 4-Pyrrolidin-1-ylmethyl-phenylamine (45.4 mg, 0.258 mmol), and the mixture was stirred for 24 h at 65° C. Subsequently, the reaction mixture was cooled to room temperature and diluted with EtOAc (˜5 mL) and Hexane (˜40 mL). The precipitate that formed was collected by filtration and washed with 0° C. iPrOH (˜5 mL) to afford the title compound in 43% yield (0.060 g, 0.11 mmol).
