Reaction Steps
A mixture of 7-(2,6-dichlorobenzoylamino)-3-hydroxymethyl-2-methylbenzo[b]furan (123 mg), acetic anhydride (43 mg) and pyridine (48 mg) in dichloromethane (5 ml) was refluxed for 2 hours. The reaction mixture was washed with 1N-hydrochloric acid, brine and aqueous saturated sodium bicarbonate, dried over sodium sulfate and evaporated in vacuo. The residue was crystallized from diethyl ether to give 3-acetoxymethyl-7-(2,6-dichlorobenzoylamino)-2-methylbenzo[b]furan (115 mg).
