Abstract
Using piperidine-4-carboxylic acid and ethanol as raw material, 4-ethyl formate piperidine was synthesized through esterification reaction with thionyl chloride and trimethylchlorosilane respectively, the yield was 85.0% and 92.7% correspondingly, the purity both reached 99%. Meanwhile, the amount of trimethychlorosilane and reaction temperature influencing on the reaction were discussed, and the optimum reaction conditions were obtained.
