Abstract:As a drug for the treatment of Parkinson′s disease, Opicapone was obtained using 3,4-dihydroxyl-5-nitryl-benzoic acid as the starting material followed by etherification, esterification, hydrolysis, condensation reaction with 2,5-dichlorine-N-hydroxyl-4,6-dimethyl-nicotineamidoxime, cyclization, oxidation, and debenzylation. The overall yield was 27.2% with a purity of 99.3%. This synthetic process is simple and easy for industrial operation with high yield and wide raw material sources.
Key words:3,4-dihydroxyl-5-nitryl-benzoic acid; opicapone; parkinson′s disease
