Reaction Conditions

Reaction Steps

A mixture of 43.2 g (0.08 mole) 2,7-bis(4-chloro-1,1-diethoxybutyl)xanthene, 2 g. of potassium iodide, 100 ml. of morpholine and 100 ml. tetrahydrofuran was heated for 24 hours with stirring in a Paar bomb at 110°C. After cooling, the mixture was filtered and the filtrate was evaporated to dryness. The residue was cooled, dissolved in 300 ml. of 10% HCl and refluxed for 1 hour. The solution was cooled, filtered, the filtrate made alkaline, and extracted with chloroform. The chloroform extract was evaporated to dryness and the residue was recrystallized twice from a 1:4 mixture of benzene in heptane. Upon drying under vacuum, the desired product was obtained. M.P. 110°-111.5°C.
