Versuchsvorschrift

To a solution of 3-(5-Amino-3H-isobenzofuran-1-ylidene)-5-chloro-1,3-dihydro-indol-2-one (56.5 mg, 0.189 mmol) and N,N-diisopropylethylamine (98.8 μL, 0.567 mmol) in 2.5 mL THF was added acetyl chloride (13.4 μL, 0.189 mmol). After stirring at room temperature for 3 h, the mixture was concentrated in vacuo and the solid triturated with MeOH. Filtering the mixture and rinsing with MeOH and hexanes/EtOAc (7:3) afforded the title compound (55.9 mg, 87%) as a yellow solid.
