N-bromobutanimide → HCID 21264584, compound

Participants

Reaction Steps

22.6 g (0.155 mol) of N-(2-methylphenyl)-N-methyl-cyanamide are dissolved in 300 ml of carbon tetrachloride, admixed with about 5 g of N-bromosuccinimide and 0.1 g of azodiisobutyronitrile and radiated using a UV lamp (250 W) for 5 hours with stirring. Over this period, more N-bromosuccinimide (a total of 32.9 g (0.185 mol)) is added a little at a time. The temperature increases during the reaction, until the solution boils at reflux. The reaction mixture is cooled and filtered, and the filtrate is concentrated under reduced pressure. 30 g of N-(2-bromomethyl-phenyl)-N-methyl-cyanamide of a content of 40% (HPLC) are obtained.
