93 g of bromine were added dropwise to a solution of 86 g of N,N-diethylaniline in 400 ml of acetic acid and the mixture was poured into an ice-water mixture. The mixture was extracted with methylene chloride and the organic phase was washed with aqueous sodium bicarbonate solution, dried and evaporated to dryness to obtain 125 g of 4-(N,N-diethylamino)-bromobenzene boiling at 97° C. at 0.6 mm Hg.
