To make this substance, one method can first take 1, 2-dihydro-2-oxoquinoline-4-formaldehyde as the starting material. React with diethyl malonate with an appropriate base as the catalyst.

After this reduction step, a partial structure containing amino groups can be obtained.
There are other methods. The halogen containing the quinoline structure can be synthesized first, and the halogen atom can be replaced by a suitable nucleophilic reagent through a nucleophilic substitution reaction. The nucleophilic substitution reaction requires the selection of an appropriate solvent and reaction temperature to ensure the smooth progress of the reaction and the selectivity of the product. Nucleophilic reagents can be prepared through a specific organic synthesis path, and their structures need to be precisely designed to react smoothly with halogenated quinoline.
