Paragraph 0096; 0115-0120, (2020/04/17)
The invention discloses a synthesis method of a nitrogen-containing deuterated methyl compound. The method comprises the following steps: 2-amino-6-methylpyridine used as an initial raw material reacts with an aprotic solution of N-bromosuccinimide, separation is performed to obtain a compound 1, the compound 1 is subjected to an iodination reaction, palladium catalysis, cyclization, hydroxyl trifluoromethanesulfonic acid anhydridization and a deuteration reaction, and then extraction, organic phase mixing, saturated salt water washing, drying, spin-drying, column separation and other post-treatments to obtain the final product. The raw material has a low cost and is easy to obtain, so compared with other synthesis routes, the synthesis method of the nitrogen-containing deuterated methyl compound has the advantages of obvious reduction of the cost, good separation effect, few impurities, suitableness for large-scale production, and increase of the demethylation synthesis yield; the deuterated product can be effectively obtained through method, the deuteration rate can reach 97%, the production temperature is not higher than 100 DEG C to easily achieve safe production, and the practical value is high.
