Procedure
The synthesis is carried out in accordance with the general procedure in accordance with Example 2 from 63.3 g (240 mmol) of 1,2-dibromo-4,5-dimethylbenzene and 85.4 g (505 mmol) of 4-aminobiphenyl. The precipitated solid is recrystallised from toluene/acetonitrile (5:1), and the residue is washed with MeOH, giving 80.3 g (182 mmol) of a crystalline solid. The overall yield is 76%.
Workup
- customThe precipitated solid is recrystallised from toluene/acetonitrile (5:1)
- washthe residue is washed with MeOH
