To prepare 1H-imidazole-2-formonitrile, 4-chloro-5- (4-methylphenyl), the following ancient method can be used.
First take the appropriate raw materials, based on 4-methylbenzaldehyde and malonitrile, add an appropriate amount of catalyst, such as piperidine, in a suitable solvent. Control the temperature at a moderate degree, often warm, so that the reaction is slow. This step aims to make 4-methylbenzaldehyde and malonitrile condensate first to produce the key intermediate. During the reaction, it is necessary to add stirring frequently to promote the material to fully contact and make the reaction uniform.
After the first step of the reaction is completed, mix the resulting intermediate with an appropriate chlorination reagent, such as phosphorus oxychloride. In this process, it is also necessary to pay attention to the temperature and time of the reaction. If the temperature is too high or side reactions occur, if it is too low, the reaction will be delayed. Maintain appropriate reaction conditions to allow the chlorination reaction to proceed smoothly, so that the intermediate can be precisely chlorinated to obtain the key product containing chlorine.
Then, the chlorine-containing product is reacted with cyanamide reagents in a specific reaction system. This system may require specific solvents, bases and other additives to create an environment conducive to the construction of imidazole rings. Control the reaction process, timely monitoring, until the reaction reaches the expected level, through a series of post-processing methods, such as extraction, washing, recrystallization, etc., to purify the product, and finally obtain 1H-imidazole-2-formonitrile, 4-chloro-5 - (4-methylphenyl). Each step requires fine operation, pay attention to the changes in the reaction conditions, in order to obtain the desired results.
