3.0 Gm. of 2-(5,5-ethylenedioxy-5H-dibenzo[a,d]cyclohepten-2-yl)propionitrile is refluxed for 3 hours in 50 ml. of water and 10 ml. of methanol containing 0.55 gm. of potassium hydroxide. The solution is cooled and extracted with ethyl acetate. The extract is washed with aqueous sodium carbonate and water, then dried and evaporated to yield 57% of 2-(5,5-ethylenedioxy-5H-dibenzo[a,d]cyclohepten-2-yl)propionamide. Use of 2-(5,5-ethylenedioxy-5H-dibenzo[a,d]cyclohepten-2-yl)acetonitrile and a 1 hour reaction time gives a similar yield of 2-(5,5-ethylenedioxy-5H-dibenzo[a,d]cyclohepten-2-yl)acetamide.
