Procedure
A mixture of 5.2 g (22 mmole) of 3,4-dihydro-1-phenyl-5H-2-benzazepin-5-one and 43 ml of dimethylformamide dimethyl acetal was refluxed for 4 hr. The mixture was concentrated at reduced pressure to dryness. The residue was crystallized with ether to give a yellow solid, mp 131°-133° C. Recrystallization from ether gave yellow prisms, mp 131°-132° C.
