Abstract:Istradefylline was synthesized from 3,4-dimethoxycinnamic acid through a series reactions including condensation, cyclization and methylation reaction. The total yield was 61.3% with a purity of 99.8%. The structure of the target compound was confirmed by MS and 1H NMR. This improved synthetic route has advantages including simple operation, low cost and high yield and is suitable for industrialized production. |
Key words:Istradefylline; improvement; 3,4-dimethoxycinnamic acid; cyclization; methylation |
