Paragraph 0030-0035; 0042-0047; 0054-0059, (2021/11/19)
The embodiment of the invention discloses a synthesis method of 3-methoxyquinoline-5-amine, relates to the technical field of synthesis of heterocyclic compounds, and aims to effectively synthesize the 3-methoxyquinoline-5-amine. The synthesis method comprises the following steps: taking 5-bromo-3-methoxyquinoline and benzophenone imine as raw materials, carrying out a coupling reaction at 45-120 DEG C to obtain an intermediate compound, and treating the intermediate compound at 25-30 DEG C by using hydroxylamine hydrochloride under an alkaline condition to obtain 3-methoxyquinoline-5 amine. The synthesis method provided by the embodiment of the invention is used for synthesizing the quinoline compound.

Bromoquinolines (2-bromoquinoline – 8-bromoquinoline and 5-bromo-3-methoxyquinoline) and 2-aminophenylboronic acid hydrochloride were subjected to Suzuki-Miyaura cross-coupling conditions resulting in formation of the desired biaryl systems in good yields. The resulting biaryls were then subjected to palladium catalyzed C–H activation/C–N bond formation utilizing PdCl2(dppf). The reactions revealed large differences in reactivity depending on the attachment point for the 2-aminophenyl group on the quinoline. The variation in the reactivity was rationalized based on the electron distribution around the quinoline ring-system.
