[Aims] The paper aims to study a more simple and efficient synthesis process for SYP-9625. [Methods] It was prepared by using 2-（4-（tert-butyl）phenyl）acetonitrile as starting material through condensation and acylation reactions. [Results] Under the new conditions, the total yield was 77% based on 2-（4-（tert-butyl）phenyl）acetonitrile and the purity was above 98%. [Conclusions] This process has the advantages of high yield, economical and simple operation, which is suitable for industrial scale manufacture.
