Versuchsvorschrift
19.1 g of bromine are added dropwise at 0° C. over 1 hour to a suspension of 24.1 g of 2,6-diisopropylaniline hydrochloride in 250 ml of 1,2-dichloroethane. The reaction mixture is stirred for 1 hour at 0° C. and then filtered. The filter residue is washed with 1,2-dichloroethane and then dried at 40° C. under vacuum, affording 36.8 g (97% of theory) of 4-bromo-2,6-diisopropylaniline hydrobromide in the form of yellow crystals which melt at 235°-237° C. after recrystallisation from ethyl acetate.
