Bromoacetophenone (I) was converted into a cis/trans mixture of ketals (III) by treatment with glycerin (II) and p-toluenesulfonic acid. Subsequent reaction of (III) with 2-naphthalenesulfonyl chloride gave the corresponding mixture of sulfonate esters. After separation of the desired cis-isomer (IV), its condensation with the phenol derivative (V) produced ether (VI). Finally, displacement of the bromine atom of (VI) with 3-mercapto-4-methyl-1,2,4-triazole (VII) using Na2CO3 in DMF gave rise to the title thioether.
