300 mg (0.83 mmole) of p-(5,6,7,8-tetrahydro-5,5,8,8-tetramethyl-2-anthracenyl) benzoic acid obtained in Example III above are dissolved in THF. 48 mg (1.25 mmoles) of LiAlH4 are added and the mixture is stirred initially for 15 minutes at ambient temperature and then for 10 minutes at reflux. The mixture is then left to stand until its temperature returns to ambient temperature. 28 μl of a saturated solution of sodium and potassium tartrate are then added. The mixture is then filtered and the THF is evaporated. The resulting residue is taken up in hexane and the precipitate that forms is filtered, yielding 167 mg (57% yield) of the expected alcohol which melts at 131° C.
