Procedure

Acetyl chloride (4.09 mL, 0.0575 mol) was added to a slurry of aluminum trichloride (AlCl3) (35.36 g, 0.265 mol) in carbon disulfide (CS2) (250 mL). After 2-3 min, 6-methoxyoxindole (7.22 g, 0.0442 mol) was added. The resulting mixture was heated to reflux for 2.5 hours. (A black tar developed with time). Excess solvent was decanted and ice water was added carefully to the residue. The resulting mixture was stirred overnight. The pale yellow solid obtained was collected, washed with water and dried under high vacuum to give the title compound (7.32 g, 87%).
