The synthesis method of 4-methyl-2-pyridinitrile has been known in ancient times, and is described in detail as follows.
First, 4-methylpyridine is used as the starting material. First, it is combined with a suitable halogenating agent, such as bromine or chlorine, under suitable reaction conditions, such as light or in the presence of an initiator, and a halogen atom is introduced at the 2-position of the pyridine ring to obtain 2-halo-4-methylpyridine. After the halide is combined with a cyanide reagent, such as potassium cyanide or sodium cyanide, in a suitable solvent, such as dimethylformamide (DMF), and under heating conditions, a nucleophilic substitution reaction occurs, and the halogen atom is replaced by a cyanyl group, resulting in 4-methyl-2-pyridineformonitrile. The steps of this method are clear, but during the halogenation reaction, side reactions may occur, forming polyhalogenated products, which affect the yield and purity.
Second, start from 2-methyl-5-nitropyridine. First, the nitro group is reduced to an amino group by a suitable reducing agent, such as iron and hydrochloric acid, or by catalytic hydrogenation, to obtain 2-methyl-5-aminopyridine. After that, the amino group is diazotized, such as sodium nitrite and hydrochloric acid at low temperature, to form a diazonium salt. Then the diazonium salt is reacted with a cyanide reagent such as cuprous cyanide, and the diazonium group is replaced by a cyanide group to obtain the target product 4-methyl-2-pyridineformonitrile. This path has a little more steps, but the reaction selectivity of each step is relatively good. If it is properly operated, a higher purity product can be obtained.
Third, the condensation reaction of pyridine derivatives is used. Select suitable pyridine derivatives with active functional groups, and react with cyano- and methyl-containing reagents in a specific reaction system under the action of basic catalysts. This method requires precise design of the structure and reaction conditions of the reactants in order to effectively achieve the synthesis of the target product. Although the process is complicated, it may be a feasible method for specific synthesis strategies.
All synthesis methods have advantages and disadvantages. In practical application, it is necessary to carefully choose according to many factors such as the availability of raw materials, cost, difficulty in controlling reaction conditions, and requirements for product purity and yield.

4-Methyl-2-pyridineformonitrile is a chemical substance, and many matters need to be paid attention to during storage and transportation.
First word storage. This chemical should be stored in a cool and ventilated warehouse. Because it is easy to change its properties and even cause danger when heated, it is necessary to avoid heat. And the humidity in the warehouse also needs to be properly controlled. If the humidity is too high, the substance may absorb moisture, which will affect its purity and stability. In addition, it should be stored separately from oxidants, acids, bases, etc., and must not be mixed. When 4-methyl-2-pyridineformonitrile encounters with these substances, it may cause a violent chemical reaction, causing explosion and other dangers. At the same time, the warehouse needs to be equipped with corresponding varieties and quantities of fire fighting equipment and leakage emergency treatment equipment for emergencies. The storage area should also be equipped with suitable materials to contain leaks.
Times and transportation. Before transportation, be sure to ensure that the packaging is complete and sealed. If the packaging is damaged and the material leaks, it will not only pollute the environment, but also endanger the safety of transportation personnel. During transportation, it is necessary to ensure that the container does not leak, collapse, fall or damage. Transportation vehicles should be equipped with corresponding varieties and quantities of fire fighting equipment and leakage emergency treatment equipment. The choice of driving routes should also be cautious, and sensitive areas such as densely populated areas and water source protection areas should be avoided. During transportation, it should not be mixed with oxidants, acids, alkalis, etc., to prevent accidental reactions on the way. In addition, transportation personnel need to undergo professional training, be familiar with the precautions during transportation, and strictly abide by the operating procedures.
