What is the preparation method of 1- (4-fluorobenzyl) piperazinediium?

The preparation method of 1 - (4 -fluorobenzyl) piperazine diammonium is as follows:
First take an appropriate amount of 4-fluorobenzyl halide, usually 4-fluorobenzyl chloride or 4-fluorobenzyl bromide. Place it in a suitable reaction vessel, which needs to be clean and dry to prevent impurities from interfering with the reaction.
Take another piperazine. According to a certain stoichiometric ratio, the molar ratio of piperazine to 4-fluorobenzyl halide is usually controlled within a certain range, about 1.0-1.2:1. Add piperazine slowly to the reaction vessel containing 4-fluorobenzyl halide. This process should be carried out under gentle stirring to make full contact between the two.
The reaction system needs to be controlled at a suitable temperature, generally between 50 and 80 ° C. It can be precisely controlled by heating in an oil or water bath. Maintain this temperature and continue to stir the reaction for several hours, about 3 to 6 hours. Pay close attention to system changes during the reaction process.
After the reaction is completed, the reaction mixture is cooled to room temperature. Then, an appropriate amount of organic solvent, such as ether or ethyl acetate, is added to extract the product. Extract several times to ensure that the product is fully transferred to the organic phase.
Combine the organic phases and dry them with anhydrous sodium sulfate or magnesium sulfate to remove the residual moisture. After filtering to remove the desiccant, distill under reduced pressure to remove the organic solvent to obtain a crude product.
The crude product can be further purified by column chromatography or recrystallization. During column chromatography, choose a suitable eluent, such as a solution of petroleum ether and ethyl acetate mixed in a certain proportion. For recrystallization, choose a suitable solvent, such as ethanol or acetone. After multiple crystallization operations, high purity 1 - (4 -fluorobenzyl) piperazine diammonium can be obtained.
