Cyclohepta[<I>b</I>][1,4]benzoxazine and 2-(<I>o</I>-hydroxyanilino)tropone were obtained by the reactions of 2-chloro- and 2-methoxytropone with <I>o</I>-aminophenol. A similar reaction with <I>o</I>-methoxylaniline gave 2-(<I>o</I>-methoxyanilino) tropone and 1-(<I>o</I>-methoxyanilino)-7-(<I>o</I>-methoxyphenylimino)-1,3,5-cycloheptatriene. The chemical and physical properties of cyclohepta[<I>b</I>][1,4]benzoxazine were discussed.
