Regioselective bromination of 5-methylthieno[2′,3′:4,5]pyrrolo[1,2-d][1,2,4]triazin-8(7H)-one (I) at 2 or 9-position was achieved by modulating the basicity of the reaction conditions. An anion directed site-specific bromination mechanism was proposed. In addition, a one-pot bromination-Suzuki coupling protocol was developed for quick access of analogs at 9-position, II [Ar = Ph, C6H4F-4, C6H4Cl-4, C6H4(CF3)-4, C6H4OMe-4, C6H4Me-3, C6H4Me-2, 1-methylpyrazin-4-yl, thien-2-yl, pyridin-3-yl].
