intramolecular amidation, has been established for efficient synthesis of 2H-1,4-benzoxazin-3-(4H)-ones from o-halophenols and 2-chloroacetamides. A varity of substrates afford the desired products in good to excellent yields. It is particularly attractive for synthesis of a library of 2H-1,4-benzoxazin-3-(4H)-ones.
