実験手順

A mixture of 40.7 g (0.10 mole) of 2,7-bis(4-chlorobutyryl)-thioxanthene, 1 g of potassium iodide and 200 ml of piperidine was stirred and heated on a steam bath for 72 hours. Upon cooling the solution was poured into 1 liter of water. The oily product obtained was dissolved in chloroform, washed with water then saturated NaCl solution, dried over magnesium sulfate and filtered. The filtrate was evaporated to a small volume, cooled, acidified to Congo Red with ethereal HCl and filtered. The resulting solid was recrystallized several times from ethanol to give the desired product. M.P. 229°-231°C.
