To prepare 2 - (2,4 - dioxynaphthalene) pyridine-1 - ethyl acetate, the following ancient method can be used.
Prepare all kinds of raw materials first, and obtain 2,4 - dioxynaphthalene, pyridine, ethyl acetate and all kinds of reagents.
In a clean kettle, dissolve 2,4 - dioxynaphthalene with an appropriate amount of solvent, such as anhydrous ethanol or dichloromethane, slowly heat until it is completely dissolved, and keep the temperature in the kettle at a suitable range. This range depends on the characteristics of the raw material and the reaction law, or between 40 and 60 degrees Celsius.
Then, add pyridine to the kettle slowly according to a certain proportion, and pay close attention to the reaction situation in the kettle when adding time to prevent excessive reaction. When pyridine enters, stir evenly to make the two fully blend.
When the two are miscible and stable, add ethyl acetate in the appropriate ratio, drop by drop into the kettle, add it, and increase the kettle temperature, so that the reaction can be carried out at a higher temperature, or between 80 and 100 degrees Celsius, and continue to stir to promote the reaction smoothly.
When the reaction is completed, the reaction process should be judged by the observation methods of the ancient method, such as observing the color change, smelling the odor change, or perceiving the slight changes in the temperature and pressure in the kettle based on experience.
When the reaction is asymptotically terminated, follow the separation and purification techniques of the ancient method, or use the method of distillation to remove the solvent first, and then fractionate to obtain pure 2- (2,4-dioxynaphthalene) pyridine-1-acetate ethyl ester. During the operation, the ancient regulations must be strictly followed, and the preparation can only be achieved with caution.
