What is the chemical synthesis method of 3,5-diiodo4-hydroxy-β-phenylalanine?
To prepare 3% 2C5-dibromo-4-fluorobenzyl - β - phenylalanine, the method is as follows:
First take an appropriate amount of β-phenylalanine and place it in a clean reaction vessel. Dissolve it in a suitable organic solvent, such as dichloromethane or N, N-dimethylformamide, etc., to make a uniform solution.
In this solution, slowly add a brominating agent, such as bromine or N-bromosuccinimide (NBS). In addition, pay attention to the control of the reaction temperature, and it should be maintained at a low temperature, such as between 0 ° C and 5 ° C, to prevent overreaction. The amount of brominating reagent needs to be accurately calculated according to the amount of β-phenylalanine. Generally, a slight excess is appropriate to allow the bromination reaction to proceed fully. When the brominating reagent is added, it can be slowly warmed to room temperature and stirred continuously for several hours to make the reaction complete. After testing the progress of the reaction and confirming the completion of the brominating reaction, the reaction solution is treated. For example, wash with an appropriate amount of lye, remove the unreacted brominating reagent and by-products, and then remove the water with a desiccant such as anhydrous sodium sulfate. After filtration, the organic solvent is removed by rotary evaporation to obtain a crude product containing brominated products.
Dissolve the crude product again and carry out the fluorination reaction with an appropriate fluorine substitution reagent. Fluorinated reagents can be selected from potassium fluoride, etc., and a phase transfer catalyst, such as tetrabutylammonium bromide, is often added to promote the transfer of fluoride ions and improve the reaction efficiency. The reaction temperature and time also need to be finely regulated. Usually, the reaction temperature is between 50 ° C and 80 ° C, and the reaction takes several hours. After the fluoride reaction is completed, the reaction solution is post-processed again, such as extraction, washing, drying, rotary steaming, etc., to obtain the crude product containing the target product.
Finally, the crude product is purified. Column chromatography can be used, using silica gel as the stationary phase, and an appropriate eluent, such as a mixed solvent of petroleum ether and ethyl acetate, can be selected. Adjust the ratio of the two according to the polarity of the target product. After column chromatography, the fractions containing the target product were collected, and the eluent was removed by rotary evaporation to obtain pure 3% 2C5-dibromo-4-fluorobenzyl - β - phenylalanine. During the whole synthesis process, attention should be paid to the control of the conditions of each reaction step to improve the yield and purity of the product.
