6-Chloro-3-pyridyl acetonitrile is an important compound in organic synthesis. The methods of its synthesis have been various, and they are described below.
First, 6-chloro-3-pyridyl carboxylic acid is started. First, it is heated with thionyl chloride and acidized to an acid chloride. This acid chloride reacts with sodium azide, rearranges by Curtius to obtain isocyanate, and then hydrolyzes it to obtain 6-chloro-3-pyridyl methylamine. Methylamine is condensed with bromoacetonitrile to obtain 6-chloro-3-pyridyl acetonitrile. < Br >
Second, 6-chloro-3-methylpyridine is used as the starting material. Using an oxidizing agent such as potassium permanganate, methyl is oxidized to a carboxyl group to form 6-chloro-3-pyridinecarboxylic acid. Subsequent to the previous method, the acid chloride is first prepared, and the amine is obtained by rearrangement and hydrolysis, and then the target is obtained by reacting with bromoacetonitrile.
Third, 3-cyano-6-chloropyridine is used as the base. React with halogenated acetonitrile, such as bromoacetonitrile, in the presence of a base, such as potassium carbonate, in a suitable solvent, such as aceton The alkali grabs the active hydrogen of 3-cyano-6-chloropyridine to generate carbon anions, which nucleophilically attack the halogenated carbon of bromoacetonitrile to obtain 6-chloro-3-pyridine acetonitrile.
Or, with suitable pyridine derivatives, chlorine atoms are introduced by halogenation, and then cyanomethyl atoms are introduced at appropriate positions. For example, a substituent is introduced at a specific position in the pyridine ring first, and the chlorine atom is precisely placed in the 6 position through halogenation reaction, and then the cyanomethyl group is added through nucleophilic substitution and other reactions to form 6-chloro-3-pyridine acetonitrile. The process of synthesis has its own advantages and disadvantages, depending on the availability of raw materials, the conditions of reaction, and the high or low yield.

6-Chloro-3-pyridyl acetonitrile is an important chemical in organic synthesis. When storing and transporting, there are many key points that need careful attention.
First of all, storage, this substance should be stored in a cool, dry and well-ventilated place. Because it is more sensitive to heat, if it is in a high temperature environment, it may cause chemical reactions, cause deterioration or risk safety. Be sure to keep away from fires and heat sources and avoid direct sunlight. In addition, it should be stored separately from oxidants, acids, bases, etc., and must not be mixed to prevent mutual reaction. Due to its certain toxicity and irritation, the storage area needs to have good leakage emergency treatment equipment and suitable containment materials. If there is a leak, it can be properly handled in time to avoid the expansion of the harm.
As for transportation, ensure that the packaging is complete and well sealed before transportation. The packaging materials must be able to effectively prevent the leakage and volatilization of the substance. During transportation, the relevant transportation regulations must be strictly followed, and it is not allowed to be mixed with contraband items. Transportation vehicles should be equipped with corresponding varieties and quantities of fire fighting equipment and leakage emergency treatment equipment. When driving, it is necessary to prevent exposure to the sun, rain and high temperature. If a leak occurs during transportation, drivers and passengers should quickly evacuate to a safe area and deal with it strictly in accordance with the emergency plan.
In conclusion, the storage and transportation of 6-chloro-3-pyridyl acetonitrile must be treated strictly, and the relevant norms and requirements must be strictly followed to ensure the safety of personnel, the safety of the environment, and the quality of the substance itself.
