该中间体在本合成路线中的序号：(I)Coupling of chloroquinazoline (I) with 3-bromoaniline (II) in refluxing isopropanol yielded anilinoquinazoline (III). The nitro group was then reduced with Fe dust and AcOH in aqueous ethanol to give amine (IV). Finally, condensation with acrylic acid (V) using 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide.HCl (EDC) in DMF provided the target acrylamide.
