To prepare 2 - [1 - (2,6 - dichlorophenoxy) ethyl] - 4,5 - dihydro - 1H - imidazole hydrochloride (1:1), the method is as follows:
First take an appropriate amount of 2,6 - dichlorophenol, placed in a clean reactor, with an appropriate amount of alkali, such as sodium hydroxide solution, adjust its pH to alkaline, so that the phenolic hydroxyl group into sodium phenol form, this step is to activate the phenolic hydroxyl group to make it more nucleophilic. < Br >
Take another ethylene oxide, slowly add it dropwise to the above reaction system containing sodium phenol, and control the temperature in a suitable range, about 40-60 ° C. This reaction undergoes nucleophilic substitution. The oxygen of sodium phenol nucleophilic attacks the carbon of ethylene oxide, and the ring is opened to form 2- (2,6-dichlorophenoxy) ethanol.
Mix 2- (2,6-dichlorophenoxy) ethanol with hydroxylamine hydrochloride in the reaction vessel, add an appropriate amount of catalyst, such as p-toluenesulfonic acid, and heat it up to 80-100 ° C. The hydroxyl group is replaced by an oxime group to form 2- (2,6-dichlorophenoxy) acetaldoxime. Subsequently, with a suitable reducing agent, such as lithium aluminum hydride, in an inert environment without anhydrous ether, 2- (2,6-dichlorophenoxy) acetaldoxime is reduced, and the oxime group is reduced to an amino group to give 2- (2,6-dichlorophenoxy) ethylamine. < Br >
Take an appropriate amount of glyoxal and formaldehyde, and place it in a reactor with 2- (2,6-dichlorophenoxy) ethylamine. With an appropriate amount of acid as a catalyst, such as acetic acid, react at 50-70 ° C, and generate 2- [1- (2,6-dichlorophenoxy) ethyl] -4,5-dihydro-1H-imidazole through cyclization.
Finally, the 2 - [1 - (2,6 - dichlorophenoxy) ethyl] - 4,5 - dihydro - 1H - imidazole is dissolved in an organic solvent, such as ethanol, into the dried hydrogen chloride gas, a salt reaction, after cooling, crystallization, filtration, drying, etc., to obtain 2 - [1 - (2,6 - dichlorophenoxy) ethyl] - 4,5 - dihydro - 1H - imidazole hydrochloride (1:1). The whole synthesis process requires attention to the precise control of the reaction conditions, and the intermediates in each step need to be purified to improve the purity and yield of the target product.

2 - [1- (2,6-dichlorophenoxy) ethyl] -4,5-dihydro-1H-imidazole hydrochloride (1:1) is a special chemical substance, and it is necessary to pay attention to its safety precautions.
This substance may be toxic to a certain extent. During operation, it must not be directly contacted, nor should it come into contact with skin and eyes. If it comes into contact with skin, rinse with plenty of water immediately and seek medical attention as soon as possible; if it spills into the eyes, rinse with plenty of running water immediately, and then seek professional medical assistance.
During use, be sure to ensure that the environment is well ventilated. Because it may volatilize harmful gases, if the ventilation is not smooth, harmful gases will accumulate, which may cause damage to the human body.
