N-Bromosuccinamide → HCID 20333849, compound

Participants

Reaction Steps

A mixture of 22.6 g (0.07 mole) of 2-bromo-5-chloro-3-(3-methylphenyl)benzofuran, 12.5 g (0.07 mole) of N-bromosuccinamide in 500 ml of carbon tetrachloride is irradiated and heated with a sun lamp for about 20 hours. The reaction mixture is filtered hot and the filtrate is allowed to cool. A solid forms which is collected, washed with carbon tetrachloride, and dried, then recrystallized from ethyl acetate to provide white product, 2-bromo-3-(3-bromomethylphenyl)-5-chlorobenzofuran, which is used directly in the next step.
