Example 1. Synthesis of 3-bromo-7,12-diphenylbenzo[k]fluoranthene
To a solvent mixture of 50 mL of N-methylpyrrolidone (NMP) and 500 mL of dichloromethane were added 10.0 g (25 mmol) of 7,12-diphenylbenzo[k]fluoranthene (see WO2010/031833 for preparation) and 6.45 g (36 mmol) of N-bromosuccinimide (NBS). The reaction mixture was stirred at room temperature for 20 hours. Upon completion of the reaction, the dichloromethane was evaporated under reduced pressure and the product was subsequently precipitated by addition of water. The precipitate was collected by filtration and dried to give 12.1 g (quantitative yield) of the title compound as a beige solid. Thin layer chromatography (TLC) analysis showed an Rf value of 0.9 (unfolding agent ratio petroleum ether:toluene = 2:1). | [References]
