Participants

Reaction Conditions

Reaction Steps

A mixture of 28.0 g (0.072 mole) of 2,8-bis(4-chlorobutyryl)dibenzothiophene, 49.4 g (0.58 mole) of piperidine and 2.0 g of potassium iodide in 200 ml of tetrahydrofuran is heated at 125°C with stirring for 24 hours in a Parr general purpose bomb. The reaction mixture is cooled, filtered, and the filtrate is evaporated in vacuo leaving a residue which is washed with water and recrystallized twice from acetone to give 2,8-bis(4-piperidinobutyryl)dibenzothiophene, M.P. 93°-95°C.
