実験手順

A mixture of 2H-3,1-benzoxazine-2,4(1H)-dione (20 g) and 3,4-dichlorobenzylamine (16.4 ml) in benzene (200 ml) was refluxed for 3 hours. After cooling, the solvent was removed under reduced pressure to give a residue, which was recrystallized from n-hexane-ethyl acetate (1:2) to afford 2-amino-N-(3,4-dichlorobenzyl)benzamide (30.5 g).
