Succinic anhydride → HCID 68528479, compound

Participants

Reaction Steps

To a suspension consisting of 3,4-dichloro-3′-fluoro-4′-phenoxybenzanilide (5.05 g, 13.4 mmol) and succinic anhydride (1.48 g, 14.8 mmol) in 1,2-dichloroethane (25 mL) was added aluminum chloride (6.26 g, 47.0 mmol) under ice cooling, and the resulting mixture was stirred at the same temperature for 5 minutes, and then at room temperature for 1.5 hours. The resulting reaction solution was poured into ice water, and the resulting solid was collected by filtration. To the solid was added 50% aqueous acetone (200 mL), and the resulting solution was refluxed for 0.5 hours, then cooled. The obtained solid was collected by filtration, to thereby yield 6.30 g of the title compound.
