Aldol condensation of 4-cyanobenzaldehyde (II) with 4-cyano-acetophenone (I) in methanolic NaOH furnished chalcone (III). Subsequent addition of bromine to (III) gave dibromide (IV). This was treated with NaOMe to produce the intermediate enol ether (V), which was then condensed with the ylide generated from trimethylsulfonium iodide and NaH to afford the 2,4-diarylfuran (VI). Acid-catalyzed addition of EtOH to (VI) provided the corresponding bis(imidate) (VII). Further reaction of (VII) with isopropylamine yielded the target amidine, which was isolated as the dihydrochloride salt.
