Isoamyl (E)-3-(3,4-dimethoxyphenyl)acrylate (1) was obtained 95% yield by 2-methyl-6-nitrobenzoic anhydride (MNBA)/4-dimethylaminopyridine (DMAP)-catalyzed reaction at room temperature for 190 minutes in dichloromethane. The structure of isoamyl (E)-3-(3,4-dimethoxyphenyl)acrylate (1) was established by NMR, FTIR, and the high resolution of mass spectroscopies. In vitro sun protection factor evaluation exhibited value of 37.10 ± 0.03 which indicates that isoamyl (E)-3-(3,4-dimethoxyphenyl)acrylate (1) as a sunscreen agent with high protection.
