Reflux 2-(6-m-acetoxyphenyl-3-oxohexyl)-2-methylcyclopentane-1,3-dione (0.8 g, the product of Michael condensation of 2-methylcyclopentanedione and a mixture of 6-m-acetoxyphenyl-1-diethylaminohexan-3-one and 6-m-acetoxyphenylhex-1-en-3-one, and containing some of the corresponding free phenolic compound) in benzene (25 cc) with toluene-p-sulfonic acid (0.3 g) for 50 minutes. On cooling add ether (50 cc) and wash the mixture in turn with water, saturated aqueous potassium bicarbonate, and brine; dry over anhydrous magnesium sulfate. The residue after removal of solvent is a purple gum (0.6 g), part of which can be induced to crystallize. Dissolve a portion (0.45 g) of this gum in benzene and adsorb on an activated Fuller's earth (40 g); elute with benzene to obtain 13β-methyl-3-hydroxygona-1,3,5(10),8,14-pentaen-17-one, which one recrystallizes from diisopropyl ether, m.p. 225°-226°; ultraviolet absorption peak at 312.5 mμ (ε23,000); infrared absorption peaks at 2.99 μ, 5.81 μ, and 8.00μ. This compound has estrogenic activity, lowers the blood lipid level, and is useful as an intermediate for preparing the hormonal compounds of this invention.
