To prepare 3-pyridinecarboxylic acid, 1,6-dihydro-1-methyl-6-oxo, there are various methods. Ancient Fangjia, or follow the way of organic synthesis, with specific raw materials and reagents, obtained through several steps of conversion.
One method, often using a compound with a pyridine ring as the starting material. Under suitable reaction conditions, the desired substituent is introduced into the specific position of the pyridine ring. If a suitable halogenated pyridine is selected, a strong base is used as the medium to interact with the methylation reagent to introduce methyl groups to the nitrogen atom of the pyridine ring to form 1-methylpyridine halide. < Br >
Then, the intermediate is treated with an oxidizing agent. Common oxidizing agents, such as periodate, peroxide, etc., can oxidize specific carbon sites of the pyridine ring to form carbonyl groups to obtain 1-methyl-6-oxo pyridine derivatives.
Then, in a suitable method, a carboxyl group is introduced at the 3-position of the pyridine ring. Or with the participation of metal-organic reagents, such as Grignard's reagent, and carbon dioxide, and then acidified to form a carboxyl group at the 3-position, and finally obtain 3-pyridinecarboxylic acid, 1,6-dihydro-1-methyl-6-oxo products. < Br >
There are other methods, starting with natural products containing pyridine structures or existing compounds, through rearrangement, substitution, oxidation and many other reactions, through clever design and operation, the synthesis of this target product can also be achieved. It is necessary to pay attention to the control of reaction conditions, such as temperature, pH, reaction time, etc., which are all related to the success or failure of the reaction and the purity of the product. And the toxicity and cost of the reagents used also need to be weighed to ensure that the synthesis method is both effective and feasible.
