Versuchsvorschrift

A stirred mixture of 8-chloro-dibenz[b,f]-[1,4]oxazepine (3.35 g) and phthalic anhydride (2.13 g) in THF (40 mL) was heated to reflux for 4 days. The mixture was concentrated and the residue was triturated with ether. The precipitated solid was filtered to give the title compound as a white solid (3.84 g).
