Participants

Reaction Steps

A suspension of 1H-benzo[d][1,3]oxazine-2,4-dione (5.00 g, 30.7 mmol) and 3-bromo-2-methylaniline (5.70 g, 30.7 mmol) in xylenes (50 mL) was heated at reflux for 8 h. The solvent was removed by distillation and the residue was purified by column chromatography on silica gel (120 g), eluting with EtOAc-hexanes (gradient from 0-50%), to give 2-amino-N-(3-bromo-2-methylphenyl)benzamide as an off-white solid (2.30 g, 24% yield).
