Abstract:Using 4-methoxy-phenyl acetic acid and 3,4-dimethoxy-phenylethylamine as the starting materials, the target compound was obtained via four steps including amidation, cyclization, reduction and demethylation with a yield of 28.1%. The structure of the final product was confirmed using 1H NMR, 13C NMR, and MS. The process was simple with higher yield and a broad range of applications, and was suitable for industrial production.
Key words:4-methoxy-phenyl acetic acid; 3,4-dimethoxy-phenylethylamine; higenamine hydrocloride
