The synthetic route is as follows., SDS of cas: 155535-20-9
b) A mixture of intermediate (3), 1-bromo-2,5-pyrolidinedione (0.116 mol) and dibenzoyl peroxide (1.3g) in tetrachloromethane (400ml) was stirred and refluxed for 35 minutes, brought to room temperature and then filtered. The reaction was carried out again using the same quantities. The residues were combined. The solvent was evaporated. The residue (60g) was purified by column chromatography over silica gel (eluent: cyclohexane/EtOAc 85/5; 15-35 mum). Two pure fractions were collected and their solvents were evaporated, yielding 25 g (43%) of (+/-)-5-bromo-2-chloro-5,6,7,8-tetrahydroquinoxaline (interm. 4) and 12 g (21 %) of (+/-)-8-bromo-2-chloro-5,6,7,8-tetrahydroquinoxaline.
