合成路线1
该中间体在本合成路线中的序号:(VIII)Alkylation of 3-chloro-4-methylaniline (I) with bromoacetaldehyde diethyl acetal (II) afforded secondary amine (III). Subsequent cyclization of (III) in boiling trifluoroacetic acid/trifluoroacetic anhydride provided a (3:2) mixture of indoles (IV) and (V), from which the desired 6-chloro isomer (IV) was isolated by column chromatography, and then reduced to indoline (VI) using NaBH3CN in AcOH. 5-Aminoquinoline (VII) was treated with carbonyl diimidazole to give intermediate (VIII). This was finally coupled with indoline (VI) in DMF at 100 C to yield the corresponding urea.
