The first method is to use 3,4-dimethoxypyridine as the starting material, first with paraformaldehyde and hydrogen chloride gas in a specific solvent, such as dichloromethane, at a suitable temperature, or between room temperature and moderate heating. In this process, paraformaldehyde is depolymerized to formaldehyde, and chloromethyl-3,4-dimethoxypyridine is introduced into the 2-position of the pyridine ring under the catalysis of hydrogen chloride to obtain 2-chloromethyl-3,4-dimethoxypyridine. Subsequently, the product is reacted with hydrogen chloride gas or hydrochloric acid solution to protonate the pyridine nitrogen atom, and then the target product is 2-chloromethyl-3,4-dimethoxypyridine hydrochloride.
Another method can be obtained by the corresponding pyridine derivative through multi-step reaction. First, the substituents on the pyridine ring are modified, such as introducing or converting the methoxy group at the 3,4-position with suitable reagents. After the construction of the 3,4-dimethoxypyridine structure is completed, the desired 2-chloromethyl-3,4-dimethoxypyridine hydrochloride is prepared according to the above chloromethylation and salt-forming steps.
