This article briefly describes the research progress and mechanism of butylphthalide. It mainly analyzes the advantages and disadvantages of each synthetic route based on the existing synthetic routes of butylphthalide. After preliminary screening, two feasible synthetic routes are obtained. In-depth research is carried out to determine the final route, and then to optimize the process, increase the yield, control impurities, simplify the operation of each reaction, and then carry out the kilogram-scale amplification verification process, and finally obtain that it can be suitable for industrial production and take into account economic costs. Synthetic route with higher product yield and purity.

This paper briefly describes the research progress and mechanism of butyl benzene, mainly according to the existing synthesis route of butyl benzene, analysis of the advantages and disadvantages of each synthesis route, after the initial screening, get two feasible synthesis routes, and then carry out in-depth study to determine the final route, and then carry out process optimization, increase yield, control impurities, simplify the operation of the reactions, and then carry out the kilogram magnification verification process, and finally can be suitable for industrial production and take into account the economic costs of the synthesis route.

In this paper, the research progress and action mechanism of butylphthalide are briefly introduced. Based on the existing synthetic routes of butylphthalide, the advantages and disadvantages of each synthetic route are analyzed. After preliminary screening, two feasible synthetic routes are obtained. Then, the final route is determined by in-depth research, and then the process optimization is carried out to improve the yield, control the impurities, simplify the operation of each reaction, and then the reaction is carried out Finally, a synthesis route with high yield and purity was obtained, which was suitable for industrial production and economic cost.
