The reaction of pimelic acid monoester (I) with refluxing SOCl2 gives the corresponding acid chloride (II), which by a Friedel-Craft's condensation with benzene (AlCl3 as catalyst) is converted into 6-benzoylhexanoic acid ethyl ester (III). The reduction of (III) with NaBH4 in methanol affords 7-hydroxy-7-phenylheptanoic acid ethyl ester (IV), which is hydrolyzed with NaOH in hot THF - water to yield the corresponding free acid (V). Finally, this compound is condensed with trimethylhydroquinone (VI) by means of boron trifluoride ethearate in hot toluene.
