What is the preparation method of Benzyl L-Leucinate 4-Methylbenzenesulfonate?
The preparation method of benzyl-L-leucine ester 4-methylbenzenesulfonate is as follows:
Take L-leucine first, place it in a reaction vessel, and dissolve it in an appropriate amount of organic solvent. This organic solvent is such as halogenated hydrocarbons such as dichloromethane and trichloromethane, or alcohols such as methanol and ethanol, so that it is fully dissolved to obtain a uniform solution.
Then, slowly add benzyl alcohol to this solution. The molar ratio of benzyl alcohol to L-leucine should be precisely prepared, usually controlled between 1.0-1.5:1. After adding, adjust the temperature of the system to a suitable range, usually 20-50 ° C, and then add an appropriate amount of catalyst, such as p-toluenesulfonic acid. The amount of catalyst used is about 0.5% to 3% of the mass of L-leucine. At this temperature, the reaction is continuously stirred for about 3-8 hours. During this period, the reaction process is closely monitored, which can be monitored by means of thin-layer chromatography.
When the reaction is generally completed, the reaction solution is treated. First, wash with an appropriate amount of saturated sodium bicarbonate solution to neutralize the excess catalyst, and then wash with deionized water for multiple times to remove water-soluble impurities. Then, dry the organic phase with a desiccant such as anhydrous sodium sulfate, filter to remove the desiccant, and then distill under reduced pressure to remove the organic solvent to obtain the crude product of benzyl-L-leucine ester.
Then dissolve this crude product in a suitable organic solvent, such as ethyl acetate, acetone, etc., and then add 4-methylbenzenesulfonic acid to it. The molar ratio of 4-methylbenzenesulfonic acid to benzyl-L-leucine ester is controlled at 1.0-1.2:1. Stir the reaction at room temperature for 1-3 hours, and the precipitate slowly precipitates out. When the precipitate is complete, sieve, wash the precipitate with cold organic solvent, and then dry it in a vacuum oven. Finally, the pure product of benzyl-L-leucine ester 4-methylbenzenesulfonate can be obtained.
