合成路线图解说明: The condensation of 4,5-dichloro-1,2-phenylenediamine (I) with diethyl oxalate (II) produced quinoxalinedione (III), which was brominated with PBr5 at 155 C to afford the dibromo derivative (IV). Displacement of one bromine group of (IV) with 4-(diethylamino)butylamine (V) furnished (VI). The remaining bromine of (VI) was then displaced with 5-(tributylstannyl)-2,2'-bithienyl (VII) to produce the title compound, isolated as the corresponding hydrochloride salt.
