N-bromobutanimide → HCID 20380612, compound

Participants

Reaction Steps

A mixture of 4-chloro-3,5-dinitro-o-xylene (4.62 g; 0.02 mol), N-bromosuccinimide (3.90 g; 0.022 mol) and carbon tetrachloride (100 ml) is stirred and heated at reflux for 4 hours. The reaction mixture is then irradiated with a light source (60 watt) and refluxing continued for 2 hours. Next, 100 mg of initiator [2,2-azobis(2-methylpropionitrile)] is added and the mixture refluxed for one more hour. The reaction mixture is then cooled to room temperature and stirred under a light source for 48 hours, and filtered. The filtrate is evaporated to dryness in vacuo, and the solid residue recrystallized twice from ethanol to afford 1.35 g of title product.
