Procedure

Trans-1,2-cyclohexanedicarboxylic anhydride (6.76 g , 0.044 mole) was heated with 1-phenylheptane (100 ml) and anhydrous aluminum chloride (12.86 g, 0.096 moles) at 100° C. for 1 hour. The reaction mixture was then poured into a mixture of ice water (500 ml) and concentrated hydrochloric acid (50 ml). The product was extracted with ether (2×200 ml) and the extracts dried over magnesium sulfate and filtered. The ether was removed under reduced pressure and the remaining solution chromatographed on silica (hexane and then hexane:ether:acetic acid at 70:30:1) to yield trans-2-(4-heptylbenzoyl) cyclohexane-1-carboxylic acid (7.36 g), m.p. 91°-94° C.
