The crude ethyl α-[(diphenylmethylene)amino]-10,11-dihydro-5H-dibenzo[a,d]cycloheptene-5-acetate is mixed with 250 mL of 6N hydrochloric acid solution and heated at reflux for 2 hours. After cooling to room temperature a solid is collected by filtration, washed with water and diethyl ether, air dried, then dried at 50° C./2 mm Hg. This provides 6.43 g of the title compound; mp >280° C.
