There are several ways to synthesize methylpyridine-4-carboxylic salts. First, pyridine-4-carboxylic acid can be started from, so that it can be co-heated with methanol under acid catalysis, and an esterification reaction can be carried out. Among them, commonly used acid catalysts, such as sulfuric acid and p-toluenesulfonic acid, etc. During the reaction, the acid and alcohol are dehydrated and condensed through specific steps to form methylpyridine-4-carboxylic salts. The reaction conditions, the temperature is about 60-80 degrees Celsius, and the reaction time is long or required, depending on the specific situation.
Furthermore, 4-halopyridine can also be used as the starting material. Schilling 4-halo pyridine is carbonylated with carbon monoxide and methanol in the presence of appropriate catalysts and bases. The catalyst used is either a palladium-based catalyst or a base can be selected from potassium carbonate. This reaction goes through a complex catalytic step, the halogen atom is replaced by a carbonyl methoxy group, and the final methylpyridine-4-carboxylate is obtained. The reaction conditions are relatively harsh, and it needs to be carried out under a certain pressure and a suitable temperature. The temperature may be 100-150 degrees Celsius, and the pressure needs to be maintained within a certain range.
Another way is to use pyridine as a raw material and prepare it through a multi-step reaction. First, pyridine is substituted at a specific position, carboxyl-related groups are introduced, and then converted into methyl pyridine-4-carboxylate. This process involves a series of reactions such as electrophilic substitution, oxidation, esterification, etc. The steps are more complicated, but it is also a synthetic method. Each method has its own advantages and disadvantages. According to actual needs, consider factors such as the availability of raw materials, cost, and difficulty of reaction conditions, and choose an appropriate synthetic path.

Methylpyridine-4-carboxylic acid ester is an important compound in organic chemistry. Its physical properties are particularly critical, and it is related to many chemical processes and practical applications.
First of all, its appearance, under room temperature and pressure, is mostly colorless to light yellow liquid, with a clear and transparent texture, like glaze, which is pleasing to the eye. This form is convenient for it to disperse evenly in various reaction systems and participate in chemical reactions.
Second on melting point and boiling point. The melting point is low, usually around -20 ° C, just like winter ice, which melts when warm. The boiling point is relatively high, about 210-220 ° C, like the temperature of a fire, and it needs a hot topic to boil into a gaseous state. This property determines its physical state under different temperature environments, which is of great significance in separation, purification and other operations.
Furthermore, the solubility. The compound is soluble in common organic solvents, such as ethanol, ether, etc., just like fish entering water, and fuses seamlessly. This solubility facilitates its use in organic synthesis reactions, and can be used as a good reaction medium to fully contact the reactants and accelerate the reaction process.
In addition, density is also one of its important physical properties. Its density is slightly higher than that of water, about 1.1-1.2 g/cm ³, which is like a stone sinking in water. When it comes to operations such as stratification, it can be separated from the water phase according to this characteristic.
At the same time, methyl pyridine-4-carboxylate has a certain volatility, which can be slowly volatilized in the air and emits a unique odor. Although it is not rich and pungent, it is also clearly identifiable. This odor can be used as a basis for identifying the compound in some occasions.
The above physical properties are interrelated and together constitute the physical properties of methyl pyridine-4-carboxylate, which lays a solid foundation for its application in many fields such as organic synthesis, drug development, and materials science.
