Reaction Steps

The compound is synthesised by the same procedure as Example 7 by reaction of 36 g (110 mmol) of 8,8-dimethyl-8H-10,12b-diazabenzo[a]aceanthrylene-3-boronic acid with 52 g (110 mmol) of bis-biphenyl-4-yl(4-bromophenyl)amine. The residue is recrystallised from toluene and from CH2Cl2/isopropanol and finally sublimed in a high vacuum. Yield: 65 g (95 mmol), 88% of theory, purity according to HPLC 99.9%.
