Reaction Steps
Ortho-phenylenediamine is treated with a suitably substituted bromoacetic acid derivative, such as 2-bromo-2-(3-bromophenyl)acetic acid, in basic medium, such as aqueous sodium hydroxide, which upon warming to 60° C. and then maintaining at this temperature for 30 minutes, affords the product 3-(3-bromophenyl)-1,2,3,4-tetrahydro-2-quinoxalinone as a precipitate.
