Abstract
A method has been developed for the preparation of 3-benzoyl-2-oxo-1,2-dihydroquinoxaline by the reaction of 3-(α-chlorobenzyl)-1,2-dihydroquinoxaline under Kornblum reaction conditions to the corresponding α-azido derivative and then acid fission of the latter. The structure of the target ketone has been confirmed by X-ray analysis.
