Participants

Reaction Steps

To a solution of 3-(6-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 filtered and rinsed with isopropanol and hexanes/EtOAc (7:3) to give the title compound (46.9 mg, 73%) as a yellow solid.
