6-[5-(4-Amidinophenyl)furan-2-yl]nicotinamidine (8a) was synthesized from 6-[5-(4-cyanophenyl)furan-2-yl]nicotinonitrile (4a), through the bis-O-acetoxyamidoxime followed by hydrogenation. Compound 4a was prepared via selective bromination of 6-(furan-2-yl)nicotinonitrile (2a) with N-bromosuccinimide, followed by Suzuki coupling with 4-cyanophenylboronic acid. In a similar way, diamidines 8b and 8c
