Versuchsvorschrift

In this preparation 25 ml. of thionyl chloride is added dropwise, with vigorous stirring, to a slurry of 5 g. of 5H-dibenzo[a,d]cyclohepten-5-ol in 50 ml. of anhydrous benzene containing five drops of pydridine, at about 0°C. The resulting mixture is continually stirred and allowed to heat to room temperature and then allowed to stand for 4 hours. The resulting mixture is then evaporated under vacuum to remove solvent and excess reagent affording a crystalline residue of 5-chloro-5H-dibenzo[a,d]cycloheptene which is then further dried under vacuum.
