By substituting 10,11-dihydro-5-(3-dimethylaminopropylidene)-3-methylsulfonyl-5H-dibenzo[a,d]cycloheptene (α-isomer) for the 5-(3-dimethylaminopropylidene)-5H-dibenzo[a,d]cycloheptene of Example 6, and following substantially the procedure of Example 6, Steps A. and B., 10,11-dihydro-5-(3-methylaminopropylidene)-3-methylsulfonyl-5H-dibenzo[a,d]cycloheptene (α-isomer) is obtained as a yellow oil. The product is converted to the hydrochloride that melts at 275.5°-276.5° C. (sintered, 274.5° C.) after recrystallization from methanol-ether mixtures.
