Abstract
Three new monocationic thienylpyridine derivatives 7a-c were prepared through two sequential steps. First step involved the preparation of carbonitrile derivatives 6a-c in good yields via a Suzuki coupling reaction between the bromothienyl derivative 4 and the appropriate phenylboronic acids 5a-c. Second step involved treatment of carbonitrile derivatives 6a-c with lithium bis-trimethylsilylamide, followed by de-protection step and subsequent hydrochloride salt formation. Chemical structures of the newly synthesized thienylpyridines were confirmed based on their spectral data, Infrared FT-IR, 1H-NMR and mass spectrometry.
