Reaction Steps

A 500 ml three neck round bottom flask was equipped with a mechanical stirrer, heating mantle and condenser. To the flask was added 52.5 g (0.11 mole) of 3-bromo-2-(1-isobutyl-3-methylbutoxy)-7H-benzo[de]anthracene-7-one (4), 9.2 g (0.087 mole) sodium carbonate, 16.0 g (0.13 mole) 2-aminothiophenol and 170 g DMF. The mixture was agitated well and heated at 120-130° C. for three hours. The reaction was cooled to 25° C. and 300 g water was added. The reaction mixture was extracted twice with 250 g chloroform. The organic layers were combined and washed twice with 250 g water. The solvent was removed on a rotary evaporator. The yield of crude product was 55 g of a dark brown oil which was used as such in the next step.
