There are several methods for synthesizing pyridine-3-formonitrile. One is to use pyridine-3-formonitrile as the starting material, so that it can be heated with thionyl chloride to obtain pyridine-3-formonitrile chloride. This reaction requires moderate temperature control to make it fully reacted. After obtaining pyridine-3-formonitrile chloride, it can be reacted with sodium cyanide in a suitable solvent, such as dimethylformamide, under mild conditions. After this step, pyridine-3-formonitrile can be prepared.
The second method uses 3-methylpyridine as the starting material. First, 3-methylpyridine is oxidized in an alkaline environment with a strong oxidant such as potassium permanganate to obtain pyridine-3-carboxylic acid. The subsequent steps are the same as the first method from pyridine-3-carboxylic acid, that is, through the process of acylation and cyanidation, pyridine-3-formonitrile is finally obtained.
There are also those who use 3-halogenated pyridine as a raw material. 3-halogenated pyridine is reacted with cyanide reagents such as cuprous cyanide at high temperature and under the presence of suitable ligands. This reaction requires attention to the anhydrous and oxygen-free reaction system to ensure the smooth progress of the reaction and the successful synthesis of pyridine-3-formonitrile.
Furthermore, the coupling reaction catalyzed by palladium can also be prepared. With suitable halogenated pyridine derivatives and cyanyl sources, such as zinc cyanide, under the action of palladium catalysts and ligands, in suitable solvents and temperature conditions, after careful reaction control and post-treatment, pyridine-3-formonitrile can be obtained. All these methods have their own advantages and disadvantages, and the experimenter should choose the best according to the actual needs.
