Reaction Steps

A degassed solution of 6.1 g (18 mmol) of 8,8-diphenyl-8H-indolo-[3,2,1-de]acridine in 40 ml of chloroform is cooled to 0° C., and 5 g (37 mmol) of AlCl3 are added. 3.9 g of benzoyl chloride are then added dropwise at this temperature, and the mixture is stirred for 8 h. 50 ml of water are added to the mixture, and the organic phase is separated off, filtered through silica gel and evaporated to dryness. The residue is recrystallised from toluene and from dichloromethane/isopropanol and finally sublimed in a high vacuum, the purity is 99.9%. The yield is 13.7 g (27 mmol), corresponding to 90% of theory.
