The precursor bromoether (III) was prepared by condensation of 4,4?difluorobenzhydrol (I) with 2-bromoethanol (II) under acidic conditions. Treatment of 4-bromocinnamic acid (IV) with thionyl chloride afforded acid chloride (V), which was coupled with ethylenediamine (VI) to furnish mono amide (VII). The title compound was finally obtained by alkylation of amine (VII) with bromide (III) in the presence of K2CO3.
