合成路线1
该中间体在本合成路线中的序号：(IX)a) Condensation of the phenolic compound (I) with 7-benzyloxy-6-methoxyquinolinyl triflate (II) in refluxing 2,6-lutidine affords the quinolinyl ether (III), which is O-debenzylated by transfer hydrogenation with 1,4-cyclohexadiene and Pd/C in EtOH at 65 °C, producing the 7-hydroxyquinoline derivative (IV). Finally, the hydroxyquinoline (IV) is alkylated with N-(3-chloropropyl)morpholine hydrochloride (V) by means of K2CO3 in DMF at 90 °C .
b) Direct coupling of the phenol derivative (I) with 4-chloro-6-methoxy-7-(3-morpholinopropoxy)quinoline (VI) in the presence of Pd(OAc)2, 2-(di-tert-butylphosphino)-1,1’-binaphthyl (DTBPB) and K3PO4 in anisole at 110 °C or NMP/toluene at 95 °C .
c) Acylation of the quinolinyloxyaniline intermediate (VII) with 1-(4-fluorophenylcarbamoyl)cyclopropanecarbonyl chloride (VIII) by means of K2CO3 in THF/H2O .
