A solution of 27 m moles(7.3 g) of the above 4-carbobenzoxyoxybenzoic acid and 27 m moles(5.6 g) of phosphorus pentachloride in 50 ml of ether was stirred for 24 hours at room temperature. After the reaction, deetherizing was carried out, and the obtained crystal was recrystallized from hexane, to obtain 4.5 g of 4-carbobenzoxyoxybenzoyl chloride [m.p. 65.5°-67.4° C⟧ (yield: 57%)
