Combination of the Suzuki cross-coupling and nucleophilicaromatic substitution of hydrogen (SNH) reactions proved to be a convenient method for the synthesis of C(4) and/or C(5) mono(thienyl) and di(thienyl) substituted pyrimidines from commercially available 5-bromopyrimidine. All new pyrimidines were found to be active in micromolar concentrations in vitro against H37Rv, avium, terrae, rifampicin

A novel synthetic route to novel thienoacene systems bearing a fused pyrimidine ring is proposed. The commercially available 5-bromopyrimidine is used as the starting material to obtain various dithienoquinazoline and benzo[f]thieno[3,2-h]quinazoline systems through the Suzuki crosscoupling, nucleophilic aromatic substitution of hydrogen (the SNH reaction), and finally palladiumcatalyzed intramolecular
