Preparation method of vanniklan tartrate tablets degraded impurities

The present invention proposes a method for the preparation of the degradation of impurities in the tartaric acid vareniclan tablets, with ammonium formate as a hydrogen donor, the dinitrolate is reduced under the palladium carbon catalyzed to obtain a diamidylation, the diaminolide and the aqueous solution of glyal are cyclic reaction to obtain a cyclic product, and then the cyclic product is hydrolyzed under the action of sodium hydroxide, the trifluoroacetyl group is removed to obtain a free base, and finally the free base is reacted with chloroacetic acid under the action of the alkali, and the solvent is evaporated after the end of the reaction, Add water to dissolve and adjust the pH until the solids precipitate from the aqueous phase, collect and filter the solids to dry to obtain acetic acid adducts. The present invention fills the technical gap of the current impurity preparation method, the prepared high-purity impurities can be applied as a control sample to the pharmaceutical impurity research and production quality control process of varenicline tartrate, providing a guarantee for the comprehensive quality control of the varenicline tartrate API.
