Procedure
2.0 Gm. of 2-(5,5-ethylenedioxy-5H-dibenzo[a,d]cyclohepten-2-yl)propionamide is dissolved in 50 ml. of methanol and 5 ml. of N-hydrochloric acid is added. The mixture is heated to 50°C. for 30 minutes then cooled and added to water. The solution is extracted with ethyl acetate and the extract washed, dried and evaporated to yield 80% of 2-(5H-dibenzo[a,d]cyclohepten-5-on-2-yl)propionamide which is recrystallized from methanol, m.p. 158°-159°C. Use of 2-(5,5-ethylenedioxy-5H-dibenzo[a,d]cyclohepten-2-yl)acetamide gives a similar yield of 2-(5H-dibenzo[a,d]cyclohepten-5-on-2-yl)acetamide.
