実験手順
In 70 ml of 0.5N hydrochloric acid was dissolved 4 g of 4-(4-pyridyl)cyclohex-3-enone ethyleneacetal and, 400 mg of 10% palladium-carbon was added to the solution followed by hydrogenation at normal temperature under normal pressure. After completion of the reaction, the catalyst was removed. After the system was rendered alkaline with a sodium hydroxide aqueous solution, it was extracted with methylene chloride to give 2.7 g of 4-(4-pyridyl)cyclohexanone.
