Reaction Steps

A mixture of 10 parts of 5-methylquinoxaline, 10 parts of 1,3-dibromo-5,5-dimethylimidazolidine-2,4-dione, 1.7 parts of benzenecarboperoxoic acid and 318 parts of tetrachloromethane was stirred for 16 hours at reflux temperature under 2 lamps of 250 Watt. The reaction mixture was cooled and the organic layer was decanted. The product was filtered off and dried, yielding 15.5 parts (100%) of 5-(bromomethyl)quinoxaline (interm. 1).
