Reaction Steps

150 Milligrams of 3,4,4a,5,8,9,10,10a-octahydro-1,4a-dimethyl-7-(1-methylethyl)-5,8-dioxo-2-phenanthrenecarboxylic acid was dissolved in 10 ml of ethyl acetate. Thereto was added, as a catalyst, 3 ml of an ethyl acetate suspension containing 15 mg of 10% palladium-carbon. The container inside was purged with hydrogen gas, and the contents were stirred at room temperature for 3 hours. The catalyst was removed by filtration, and the filtrate was concentrated under reduced pressure to obtain 135 mg of 3,4,4a,9,10,10a-hexahydro-5,8-dihydroxy-1,4a-dimethyl-7-(1-methylethyl)-2-phenanthrenecarboxylic acid.
