3-p-Methoxyphenylbenzothiophene is acylated with 3,5-dimethylbenzoyl chloride as previously described to give 2-(3',5'-dimethylbenzoyl)-3-p-methoxyphenylbenzothiophene. Demethylation with pyridine hydrochloride followed by reaction of the hydroxy compound thus formed with diethylaminoethyl chloride as described above gives the title compound.
