Versuchsvorschrift

A dry 100 mL flask was charged with acetyl chloride (0.408 g, 5.20 mmol) and THF (40 mL). 6-(4-Amino-benzoyl)-1,3-dihydro-indol-2-one (as prepared in Example 15, 1.00 g, 3.96 mmol) was added to the THF solution of the acid chloride, and the mixture was allowed to reflux for 3 h. The reaction mixture was then allowed to cool to room temperature. The room temperature reaction mixture was concentrated in vacuo. The brown solid residue was suspended in boiling EtOAc. The suspension was allowed to cool to room temperature before filtering to afford the N-[4-(2-Oxo-2,3-dihydro-1H-indole-6-carbonyl)-phenyl]-acetamide as a tan solid (1.16 g, 3.94 mmol, 99%).
