SYNTHESIS OF NOVEL 1-ARYL[1]BENZOXEPINO[5,4-C]PYRAZOLE AND [1]BENZOXEPINO[5,4-D]PYRIMIDINE DERIVATIVES

Several 1-aryl[1]benzoxepinopyrazoles were prepared by reaction of 4-h ydroxymethylene[1]benzoxepinones with appropriate phenylhydrazine hydr ochlorides. The direct condensation of hydroxymethylenebenzoxepinones with variously substituted amidines failed to give benzoxepinopyrimidi nes. These compounds were obtained via the key intermediates morpholin e enaminobenzoxepinones.
