Reaction Steps

The crude 2-chloro-4-{[p-(p-hexylphenyl)benzoyl]oxy}benzaldehyde (67.1 g) obtained was dissolved in 2500 ml of acetone. 80 ml of Jones' reagent were added dropwise to this solution within 45 minutes, the mixture warming slightly. The mixture was stirred for a further 3 hours, then the precipitated inorganic material was filtered off under suction and the acetone was distilled off on a rotary evaporator. The residue was suspended in water and the suspension was suction filtered. The crude 2-chloro-4-{[p-(p-hexylphenyl)benzoyl]oxy}benzoic acid obtained was washed neutral on the suction filter with water and then, for purification, boiled up with methanol, cooled, filtered off and dried. Yield 58.5 g; m.p. 163.8°-165.5° C.
