Phthalic Anhydride → HCID 54083732, compound

Participants

Reaction Steps

At 0°-3° C., 9.6 g of phthalic anhydride are added to a solution of 18 g of ethyl 10-phenyldecanoate in 100 ml of 1,2-dichloroethane, after which 26 g of aluminium chloride are added in portions over a period of 1 hour. After stirring for 20 hours at room temperature, the mixture is poured onto ice/2N hydrochloric acid and extracted with methylene chloride. Washing of the organic phase with saturated sodium chloride solution, drying and evaporation gives 25.1 g of 2-[4'-(9"-ethyoxycarbonylnonyl)benzoyl]benzoic acid as a waxy solid which can be used for the next step without purification.
