Procedure

19.2 g (0.04 mol) of 9,10-bis(4-methoxy-3-nitrophenyl)-anthracene in a mixture of 200 ml of butanone and 200 ml of concentrated HBr are refluxed for 24 h while stirring. After the end of the reaction, the suspension is evaporated down to half its volume in a rotary evaporator and the product is filtered off with suction. Recrystallization from toluene is then effected.
