The synthesis of pyridine-3-carboxyamide (pyridine-3-carboxyamide) is an important topic in chemical preparation. There are many methods, and the common ones are selected.
First, pyridine-3-carboxyamide is used as the starting material. First, pyridine-3-carboxyamide is reacted with dichlorosulfoxide, and this step aims to convert the carboxyl group into an acyl chloride. When pyridine-3-carboxyamide encounters dichlorosulfoxide, the hydroxyl group in the carboxyl group is replaced by a chlorine atom under specific reaction conditions to form pyridine-3-carboxyamide chloride. This reaction requires attention to the reaction temperature, time and the ratio of reactants. If the temperature is too high or the reaction is too long, side reactions will easily occur, resulting in impure products.
Then, the obtained pyridine-3-formyl chloride is reacted with ammonia gas or ammonia alcohol solution. The acid chloride group of pyridine-3-formyl chloride is very active. When encountering ammonia, the chlorine atom is replaced by an amino group, and then pyridine-3-formamide is obtained. This step also requires good control of conditions, such as the pH and temperature of the reaction system, in order to increase the yield.
Second, ethyl nicotinate can be used. Ethyl nicotinate is hydrolyzed under alkaline conditions, and the ester group is broken to form niacin. Subsequently, niacin is synthesized into acyl chloride through conversion steps similar to the above, and then reacted with ammonia to obtain pyridine-3-formamide. In this path, the hydrolysis step needs to select a suitable base and reaction temperature to ensure complete hydrolysis without damaging other groups.
Or, with a suitable pyridine derivative as the starting material, a carboxyl group is introduced through a specific substitution reaction, and then the amidation reaction is carried out to prepare pyridine-3-formamide. This approach requires high reaction conditions, and it is necessary to precisely control the check point and selectivity of the substitution reaction to avoid unnecessary by-products.
All synthesis methods have their own advantages and disadvantages. In practical application, the optimal synthesis path should be selected according to factors such as raw material availability, cost, product purity and yield.

Pyridine-3-formamide, or nicotinamide, is widely used in many fields such as medicine, chemical industry, and food.
In the field of medicine, its efficacy is significant. It can participate in human metabolism and help cell repair and regeneration.
