Procedure

To 5-(morpholin-2-yl)methylidene-10,11-dihydro-5H-dibenzo[a,d]cycloheptene (300 mg) in ethanol were added propargyl bromide (2.0 g) and potassium hydroxide (570 mg) in water at room temperature, and the resulting mixture was stirred at room temperature for 1 hour. After ethanol was distilled off, water was added to the residue, and the resultant mixture was extracted with chloroform. The chloroform extract was dried, evaporated and chromatographed to afford 5-(4-propargylmorpholin-2-yl)methylidene-10,11-dihydro-5H-dibenzo[a,d]cycloheptene as crystalline material. M.P., 124°-125° C.
