実験手順

A solution of 15.0 g (0.04 mole) of 3,6-bis(4-chlorobutyryl)carbazole, 85.0 g (1.0 mole) of piperidine and 2.0 g of potassium iodide in 15 ml of tetrahydrofuran is heated at 110° C. in a reaction bomb for 24 hours with stirring. Upon cooling, the reaction mixture is filtered and diluted with 700 ml of ice water. The resulting solid is washed with water, dried over magnesium sulfate and recrystallized from chloroform-petroleum ether (75°-90° C.) and then from acetone to give 3,6-bis(4-piperidinobutyryl)carbazole, M.P. 171°-173° C.
