Reaction Steps

The resulting, crude 2-chloro-4-[(p-heptylbenzoyl)oxy]benzaldehyde is dissolved in 350 ml of acetone. Within 40 minutes there are added dropwise thereto 30 ml of Jones' reagent, the mixture warming slightly. The mixture is stirred for a further 1 hour, precipitated inorganic material is then filtered off under suction, the filtrate is diluted with 300 ml of water (the product precipitating), concentrated on a rotary evaporator to about 300 ml and the suspension obtained is suction filtered. The suction filter material is washed three times with 50 ml of 10% aqueous acetone, dried and recrystallized from about 60 ml of benzene. There are obtained 13.8 g of 2-chloro-4-[(p-heptylbenzoyl)oxy]benzoic acid, m.p. 108° C. (nematic).
