Versuchsvorschrift

N,N′-dimethylethylenediamine 1.76 g was added to diphenylamine 16.9 g, 4-bromoiodobenzene 28.2 g sodium t-butoxide 14.4 g, copper powder 3.81 g and a xylene 100 ml solution, and the mixture was heated and refluxed for 24 hours under argon atmosphere. After cooled down to room temperature, the mixture was filtered to remove an insoluble matter, and the filtrate was concentrated. The residue was refined by silica gel chromatography to obtain 22.7 g of white crystal of 4-bromotriphenylamine.
