2‐Azaxanthone ( 5 ) has been conveniently prepared by condensation of the morpholine enamine of 1‐benzyl‐4‐piperidone witli salicylaldehyde followed by chromium trioxide oxidation and subsequent aromatization. Lithium aluminum hydride reduction of 5 afforded the new fundamental heterocycle 2‐azaxanlhene.
