Participants

Reaction Steps

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 acetyl chloride (13.4 μL, 0.189 mmol). After stirring at room temperature for 1 h, the slurry was partitioned between NaHCO3 solution and EtOAc (warmed to dissolve solid). The organic phase was washed with H2O, 4% aqueous HCl solution, H2O, saturated NaHCO3, brine and dried with Na2SO4. After concentrating in vacuo the residue was triturated with EtOAc to give the title compound (47.4 mg, 82%) as a yellow solid.
