Paragraph 0035; 0042-0043, (2021/02/06)
The invention relates to a preparation method of imidic acid or hydrochloride thereof, which belongs to the technical field of medicine synthesis. In order to solve the problems of easy salification and low yield in the prior art, the invention provides a preparation method of imidic acid or hydrochloride thereof, which comprises the following steps of in the presence of an acid application agent,reacting 4-halogenated methyl acetophenone with N-methylpiperazine to obtain a corresponding intermediate, under the action of pypocholoride, enabling the intermediate to be subjected to an oxidationreaction to obtain corresponding imidic acid, when the imidic acid hydrochloride is synthesized, after the oxidation reaction is finished, adjusting the pH value to be strongly acidic, so that the corresponding imidic acid hydrochloride is formed. According to the method, the reaction has the effect of high conversion rate during condensation, byproducts of salifying reaction products are effectively avoided, raw material residues can be effectively controlled to be less than 0.2%, and the method has the effect of high product yield.
