合成路线1
该中间体在本合成路线中的序号：(V)4-Chloro-7-fluoro-6-nitroquinazoline (I) was condensed with 3-chloro-4-fluoroaniline (II) to afford the 4-anilino quinazoline (III). Displacement of the activated fluorine of (III) with the potassium alkoxide of morpholinopropanol (IV) gave the morpholinopropyl ether (V). Subsequent reduction of the nitro group of (V), either using iron dust and acetic acid or catalytic hydrogenation over Raney-Ni, furnished aminoquinazoline (VI). This was finally condensed with acrylic acid (VII), via activation as the mixed anhydride with isobutyl chloroformate or using EDC as the coupling reagent, to provide the title acrylamide.
