Procedure

22 G. of 5-oxo-5H-dibenzo[a,d]cycloheptene-2-carboxylic acid is stirred in 200 ml. of chloroform, 50 ml. of thionyl chloride and 1 ml. of dimethylformamide for 8 hours. The mixture is evaporated to dryness and the residue recrystallized from acetonitrile to yield 2-chloroformyl-5-oxo-5H-dibenzo[a,d]cycloheptene.
