반응 단계
A mixture of 7-chloro-2H-3,1-benzoxazine-2,4(1H)dione (18.4 g) and 4-bromo-2-fluorobenzylamine (26 g) in tetrahydrofuran (200 ml) was refluxed for 15 minutes. After cooling, tetrahydrofuran was evaporated to give a residue. Recrystallization from isopropyl ether gave 2-amino-N-(4-bromo-2-fluorobenzyl)-4-chlorobenzamide (26.6 g).
