실험 절차
This was prepared by the method reported by Schlack and Koller in Aromatic aliphatic diketones. P Schlack and W Koller. Ger. 1,086,711 Aug. 11, 1960. The title compound was prepare by treatment of orthocresol (2.2 moles) with sebacic acid (1 mole) in the presence of polyphosphoric acid (3 moles). The mixture was stirred for 4 hrs at 80° C. and poured to ice-water after cooling. The precipitant was filtered, dissolved in ethyl acetate and washed with water three times. The solvent was evaporated to yield a crude 1,10-bis(4-hydroxy-3-methylphenyl)decane-1,10-dione which was then subjected to Clemmensen reduction to give the title compound.
