Versuchsvorschrift

To a solution of 3-(6-Amino-3H-isobenzofuran-1-ylidene)-1,3-dihydro-indol-2-one (50.0 mg, 0.189 mmol) and N,N-diisopropylethylamine (98.8 μL, 0.567 mmol) in 2.0 mL THF was added 4-chlorobutyryl chloride (21.2 μL, 0.189 mmol). After stirring at room temperature for 1 h, the slurry was filtered and rinsed with MeOH and EtOAc/hexanes (1:1) to afford the title compound (58.8 mg, 84%) as a yellow solid.
