Looking at this compound, its core structure is a six-element nitrogen-containing heterocycle, which is called the pyridine ring. In the first position of the pyridine ring, a methyl group is connected, and this methyl group is an alkyl group formed by monocarbon and trihydrogen. Looking at the sixth position, it is a carbonyl group, that is, the carbon-oxygen double bond structure, and it is in the state of oxygen, so it is called "6-oxo". In the third position, a carboxylamide group is formed by linking a carbonyl group to an amino group, and has the characteristics of a carboxyl group and an amino group. 1,6-dihydropyridine indicates that the 1,6 positions of the pyridine ring are dihydrogen states, which means that the carbon atoms of the two positions are combined with hydrogen atoms, and the double bond state of complete unsaturation is not reached.

1-methyl-6-oxo-1,6-dihydropyridine-3-carboxamide, Chinese name or 1-methyl-6-oxo-1,6-dihydropyridine-3-formamide. There are several common methods for synthesizing this compound:
First, a pyridine derivative is used as the starting material. First, a suitable pyridine compound is taken, and a methyl group is introduced at the first position of the pyridine ring through a specific substitution reaction. This substitution reaction may require specific catalysts and reaction conditions to ensure the precise introduction of methyl groups. Then, the oxidation reaction is carried out at the 6-position to convert the 6-position to a carbonyl group, thereby constructing a 6-oxo structure. Finally, a formamide group is introduced at the 3-position. This step may involve an amidation reaction. Suitable acylation reagents and reaction conditions can be selected to promote the successful access of the formamide group to achieve the synthesis of the target product.
Second, nitrogen-containing heterocycles and carbonyl compounds can also be used as starting materials. First, the nitrogen-containing heterocycle undergoes a condensation reaction with a specific carbonyl compound to form the prototype of the pyridine ring. During the reaction, some substituents on the pyridine ring, such as the methyl group at the 1-position, are constructed at the same time. Afterwards, the pyridine ring is oxidized and modified to form a carbonyl group at the After the amidation step, the formamide group is introduced at 3 positions to obtain 1-methyl-6-oxo-1,6-dihydropyridine-3-carboxamide.
Third, the strategy of gradually constructing the pyridine ring is adopted. First, the intermediate containing specific substituents is prepared by organic synthesis. Then, the pyridine ring is constructed by cyclization reaction. During the cyclization process, the structural units such as 1-methyl, 6-oxo and 3-formamide are introduced synchronously or step by step. This strategy requires fine design of reaction routes and conditions to ensure the smooth progress of each step of the reaction and the correct introduction of substituents.
Each synthesis method has its own advantages and disadvantages. In practice, the appropriate synthesis path should be carefully selected according to many factors such as the availability of starting materials, the difficulty of controlling the reaction conditions, and the purity requirements of the target product to efficiently prepare 1-methyl-6-oxo-1,6-dihydropyridine-3-carboxamide.
