N- (4-pyrrolidinyl) pyridine is an organic compound. Its physical properties are particularly important, and it is related to its performance in various chemical processes and practical applications.
In terms of its appearance, it is mostly colorless to light yellow liquid under normal conditions, clear and fluid. This color sign is its visual and recognizable image, and also implies the characteristics of its molecular structure.
As for the melting point, it is about -15 ° C. The lower melting point indicates that the intermolecular force is relatively weak, causing it to melt into a liquid state at low temperatures. The boiling point is about 240-242 ℃, and the higher boiling point reveals that higher energy is required to overcome the attractive force between molecules, so that it can be converted from liquid to gaseous state.
Its density is about 1.05-1.07 g/cm ³, which is slightly heavier than water. In systems involving liquid-liquid separation or mixing, this density characteristic has a significant impact. In terms of solubility, it is soluble in common organic solvents, such as ethanol, ether, etc. Due to the similar compatibility, its molecular structure is similar to that of organic solvents. However, its solubility in water is limited due to the difference between molecular polarity and water.
In addition, N - (4 -pyrrolidinyl) pyridine is volatile to a certain extent and will evaporate slowly in an open environment. And because its molecular structure contains nitrogen atoms, it has a weak alkalinity, which plays a key role in acid-base reactions or catalysis processes. In summary, the physical properties of N - (4 -pyrrolidinyl) pyridine lay an important foundation for its application in chemical synthesis, drug development and other fields.

To prepare N- (4 -pyrrolidinyl) pyridine, the method is as follows:
First take pyridine as the starting material, pyridine, aromatic nitrogen-containing heterocyclic compounds are also. Dissolve the pyridine into a suitable solvent, which must not interfere with the reaction, and can make the reactants evenly dispersed, such as anhydrous ether and other inert organic solvents.
Another 4-halo pyrrolidine, this halogen atom can be chlorine, bromine, etc. Add it slowly to the solution containing pyridine, and at the same time, add an appropriate amount of base. For bases, potassium carbonate, sodium carbonate and the like can be selected. The role of alkali is to neutralize the hydrogen halide generated by the reaction and promote the positive progress of the reaction.
During the reaction process, the temperature should be controlled moderately. The reaction can be started in a low temperature environment, such as about 0 ° C, and then gradually heated to room temperature, or moderately heated according to the reaction process, but not overheated to prevent side reactions. This reaction is a nucleophilic substitution. The nitrogen atom of pyridine is nucleophilic and can attack the carbon atom attached to the halogen atom of 4-halopyrrolidine. The halogen atom leaves, and then becomes the intermediate of N- (4-pyrrolidine) pyridine.
After the reaction is completed, the reaction solution is treated by the conventional separation and purification method. First, the organic phase is separated by a separation funnel, and the aqueous phase is removed. Then the organic phase is distilled to remove the solvent, and the crude product can be obtained. To obtain a pure product, it can be further separated by column chromatography, select a suitable silica gel as the stationary phase, elute with a suitable eluent, collect the fractions containing the target product, steam off the eluent, and finally obtain pure N - (4-pyrrolidine) pyridine.
Or it can be prepared by other methods, such as the reaction of 4-aminopyrrolidine with a derivative of pyridine, and the appropriate functional group transformation can also obtain this product. However, this route may require multiple steps of reaction, and each step of the reaction needs to be finely regulated to achieve higher yield and purity.
