In addition to the parent compounds, nine methyl-substituted l,Mibydro-4H-3,l-benzoxazines with and without N-methyl substitution were prepared. The chain tautomer could only be detected in the case of 1,2-dihydro-2+ nitrophenyl)-4H-3,1-benzoxazine in solution. The configurational and conformational

## Abstract Substituted 2‐(benzylamino)‐2__H__‐1,4‐benzoxazin‐3(4__H__)‐ones are unstable under alkaline and acidic conditions, undergoing opening of the benzoxazinone ring. 2‐Bromo‐2__H__‐1,4‐benzoxazin‐3(4__H__)‐ones show similar degradation under alkaline conditions, while replacement of Br at C
