A solution of 7-(3,6-dichlorophthalimido)-2,3-dimethylbenzo[b]furan (100 mg) in a mixture of aqueous 1N-sodium hydroxide (2 ml) and methanol (3 ml) was stirred at ambient temperature overnight. The reaction mixture was acidified with 1N-hydrochloric acid. The separated solid was collected, washed with water and dried to give 7-(6-carboxy-2,5-dichlorobenzoylamino)-2,3-dimethylbenzo[b]furan (60 mg).
