Participants

Reaction Steps

To 7-fluoro-8-methyl-2-(methyloxy)quinoxaline (50 g, 260 mmol) in dry chloroform (1 L) were added N-bromosuccinimide (52 g, 292 mmol) and benzoyl peroxide (70%, 0.42 g) and the mixture was heated under reflux, illuminated with a 120 W lamp, for 2 h. After cooling, the mixture was washed with water. The aqueous phase was re-extracted twice with dichloromethane and the combined organic fractions were washed with water, dried and evaporated to give product (72.1 g, 100%).
