Reaction Steps
3,4-Dimethoxy-cinnamic acid amidoxime used as starting material was prepared by the reaction of 3,4-dimethoxycinnamonitrile with hydroxylamine under the usual conditions in ethanol-water solution. The 3,4-dimethoxycinnamonitrile was obtained from 3,4-dimethoxybenzaldehyde with cyanoacetic acid in pyridine solution by literature method (J. Am. Chem. Soc. 65, 22(1943)).
