By substituting 5-(3-dimethylaminopropylidene)-3-methylsulfonyl-5H-dibenzo[a,d]cycloheptene (α -isomer), product of Example 23, Step F.), 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, 5-(3-methylaminopropylidene)-3-methylsulfonyl-5H-dibenzo[a,d]cycloheptene (α-isomer) is obtained in the form of a yellow oil. The product is converted to the hydrochloride that melts at 273°-274.5°C. (sintered, 271.5°C.) after recrystallization from mixtures of methanol and ether.
