The method for synthesizing 2- (chloromethyl) -6-methylimidazolo [1,2-a] pyridine can follow the following steps.
First take an appropriate amount of 6-methylpyridine-2-amine, place it in a clean reactor, dissolve it with an appropriate amount of organic solvent such as dichloromethane, stir well to form a homogeneous solution.
Take chloroacetaldehyde for the second time, slowly add it dropwise to the above solution, while maintaining a low temperature environment, about 0 to 5 degrees Celsius. Add it dropwise, raise it to room temperature, and continue to stir for a few times when the reaction is completed. In this process, 6-methylpyridine-2-amine interacts with chloroacetaldehyde to gradually form the precursor of the target product.
After the reaction is completed, the reaction solution is poured into the separation funnel, washed with an appropriate amount of saturated salt water, and the organic phase is separated. Then the organic phase is dried with anhydrous sodium sulfate, the desiccant is filtered off, and the desiccant is distilled under reduced pressure to remove the organic solvent to obtain the crude product.
After the crude product is separated by column chromatography, and eluted with a suitable eluent, such as a mixture of petroleum ether and ethyl acetate in a certain proportion. The fractions containing the target product are collected and concentrated by rotary distillation to obtain pure 2- (chloromethyl) -6-methylimidazolo [1,2-a] pyridine. During the operation, attention should be paid to the control of temperature, dripping speed and reaction time to ensure the smooth progress of the synthesis reaction and obtain a product with high yield and purity.

2 - (chloromethyl) -6 -methylimidazolo [1,2 - a] pyridine in storage and transportation, need to pay attention to many key matters. This substance has a certain chemical activity, when exposed to water or moisture, or chemical reaction, forming corrosive or harmful products. Therefore, it should be placed in a dry, well-ventilated place, away from water sources and moisture, and the packaging used must be waterproof.
It is flammable, and there is a risk of combustion and explosion in high temperature, open flame or strong oxidant environment. When storing, it should be isolated from oxidants, fire sources, etc. The warehouse needs to have fire and explosion-proof facilities, and fireworks are strictly prohibited. During transportation, high temperature environment and impact should also be avoided to ensure the fire safety of transportation vehicles.
Due to its chemical structure characteristics, or harmful to human health.
