Novel method for preparing drotaverine hydrochloride intermediate

The invention discloses a novel method for preparing a drotaverine hydrochloride intermediate, belonging to the technical field of medicine synthesis. The preparation method comprises the following steps: preparing an intermediate 3,4-diethoxyphenylacetic acid with 1,2-diethoxybenzene as a raw material, and preparing the intermediate 3,4-diethoxyphenylacetamide with 3,4-diethoxyphenylacetic acid as a raw material. According to the novel process for preparing the drotaverine hydrochloride intermediate, a method for directly preparing 3,4-diethoxyphenylacetic acid and 3,4-diethoxyphenylethylamine is adopted, and a process for preparing 3,4-diethoxyphenylacetonitrile is avoided, so a reaction step of using sodium cyanide is avoided.
