Procedure

A mixture of 20 g of 2,7-bis(5-chlorovaleryl)thioxanthene, 2 g of potassium iodide, 70 ml of piperidine and 150 ml of tetrahydrofuran is heated in a Paar bomb at 100° C. with stirring for 48 hours. Upon cooling, the solvent is evaporated, and the remaining material is poured into water then filtered. The residue is recrystallized several times from heptane to give 2,7-bis(5-piperidinovaleryl)thioxanthene, M.P. 98.5°-99.5° C.
