0.48 G. of a 50% mineral oil dispersion of sodium hydride is added to a solution of 2.64 g. of 2-(5-oxo-5H-dibenzo[a,d]cyclohepten-2-yl)propan-1-ol in 30 ml. of dimethylformamide. The mixture is warmed to 40° C. and stirred until hydrogen evolution ceases. 3.0 G. of ethyl iodide is added and the mixture heated to 60° C. for 3 hrs. Water and ether are added and the ethereal solution is washed with water, dried and evaporated to yield 1-ethoxy-2-(5-oxo-5H-dibenzo[a,d]cyclohepten-2-yl)propane.
