The synthesis of 2-fluoropyridine-3-formaldehyde has been known for a long time and has many kinds. Today I will describe one or two in detail.
First, it can be obtained from the oxidation of 2-fluoropyridine-3-methanol. This reaction requires the use of appropriate oxidizing agents, such as Dess-Martin reagents, which have mild oxidation and good selectivity. The reaction is carried out in a suitable organic solvent, such as dichloromethane. Under the condition of low temperature and stirring, 2-fluoropyridine-3-methanol is fully reacted with Dyce-Martin reagent. After post-treatment, such as extraction, washing, drying, column chromatography separation and other steps, pure 2-fluoropyridine-3-formaldehyde can be obtained.
Second, 2-fluoropyridine-3-carboxylic acid is used as the starting material. First, it is converted into the corresponding acyl chloride, and reagents such as thionyl chloride can be selected. This reaction is relatively rapid and the yield is quite high. The acid chloride is reduced by Rosenmund, using palladium-barium sulfate as catalyst and quinoline-sulfur as inhibitor, and hydrogen is introduced to reduce the acid chloride to aldehyde group, thereby preparing 2-fluoropyridine-3-formaldehyde. However, this process needs to strictly control the reaction conditions to avoid excessive reduction to form alcohols.
Third, halopyridine can also be used as substrate. A suitable organometallic reagent, such as Grignard reagent, reacts with the corresponding halogenated pyridine to form a pyridine-based intermediate, and then interacts with N, N-dimethylformamide (DMF). After hydrolysis, the target product 2-fluoropyridine-3-formaldehyde can be obtained. This method requires attention to the preparation and use conditions of Grignard reagents to ensure an anhydrous and anaerobic environment to improve the success rate of the reaction.
All synthesis methods have their own advantages and disadvantages. It is necessary to choose carefully according to actual needs, raw material availability and reaction conditions, etc., in order to achieve the purpose of synthesis.
