Versuchsvorschrift
Phosphorus pentoxide (1.28 g.) and concentrated (85%) phosphoric acid (2.7 ml.) are mixed well and cooled to room temperature. Potassium iodide (6.6 g., 0.04 mole), finely powdered, and 5-(3-ethoxypropyl)-3-iodo-5H-dibenzo[a,d]cycloheptene (4.0 g., 0.01 mole) are added and the mixture stirred and heated in an oil bath at 110° for 16 hours.
