Alternatively, alkylation of diclofenac sodium (I) with either trichloroethyl bromoacetate (XII) of tribromoethyl bromoacetate (XIII) gave rise to the respective trichloroethyl (XIV) and tribromoethyl (XV) esters of aceclofenac. Reductive cleavage of the trihaloethyl esters (XIV) and (XV) using zinc powder under acidic conditions furnished the title compound.
