The invention relates to an organic compound synthesis method, and relates to a process method for synthesizing N-substituted piperidine-4-boric acid, which comprises the following steps of: reactingN-substituted piperidine-4-alcohol used as a raw material with thionyl chloride and organic alkali in a solvent to generate N-substituted piperidine-4-chlorine, reacting the N-substituted piperidine-4-chlorine used as a raw material with lithium metal and bis (N, N-dimethylamino) borane halide in a solvent, quenching and acidifying to obtain N-substituted piperidine-4-boric acid. The process method has the advantages of originality, low cost, safety and mild reaction conditions, avoids the dangerous reaction that other patented methods adopt expensive palladium hydroxide hydrogenation, has potential cost advantage and safety advantage, and is suitable for industrial scale-up production.
