Potassium Iodide → HCID 12331755, compound

Participants

Reaction Steps

A mixture of 17.0 g (0.045 mole) of 2,8-bis(4-chlorobutyryl)dibenzofuran, 68.0 g (0.8 mole) of piperidine and 2.0 g of potassium iodide in 500 ml of butanone is heated at reflux for 72 hours then filtered. The filtrate is concentrated to one-half its original volume then diluted with 600 ml of water. The resulting semi-solid is purified by chromatography on neutral alumina using methylene chloride as the eluant. The solvent is removed from the fraction collected leaving a solid residue which is recrystallized from pentane to give 2,8-bis(4-piperidinobutyryl)dibenzofuran, M.P. 70°-71° C.
