Vorschrift

A mixed solution of 2.2 g of the above-mentioned 2-tert-butyl-9-(naphthalene-2-yl)anthracene, 3.7 g of N-bromosuccinimide and 30 ml of dimethylformamide was stirred under nitrogen gas stream at room temperature for 1 hour. 50 ml of water was injected thereto to extract 100 ml of dichloromethane therefrom. The organic layer was washed twice in 50 ml of water, dried by magnesium sulfate and thereafter concentrated by evaporation. The organic layer was purified by silica gel column chromatography to obtain 10-bromo-2-tert-butyl-9-(naphthalene-2-yl)anthracene.
