実験手順

In a 500-ml flask equipped with a stirrer, a thermometer and a dropping funnel were placed 34.5 g (485 mmol) of pyrrolidine, 38.4 g (485 mmol) of pyridine and 140 ml of methylene chloride. To the stirred mixture under ice-cooling in a nitrogen atmosphere, 31.4 g (97 mmol) of 1,3,5-adamantanetricarbonyl trichloride in 190 ml of methylene chloride was added dropwise over 1 hour. This was warmed to room temperature, was stirred for further 1 hour and was washed with water, 1 N hydrochloric acid, and 10% aqueous sodium carbonate solution, and the solvent was removed under reduced pressure, to yield 37.2 g (87 mmol) of 1,3,5-tris(1-pyrrolidinylcarbonyl)adamantane in a yield of 90%.
