First take the appropriate starting material, which may contain specific benzopyran and pyridine structural fragments. In the first step, the active benzopyran derivatives and pyridine reactants can be met under suitable reaction conditions by means of the common condensation reaction in organic synthesis chemistry.
This reaction requires careful selection of solvents, such as non-protic organic solvents, such as dichloromethane, N, N-dimethylformamide, etc., to create an environment conducive to the reaction. The reaction temperature is also crucial, or it can be adjusted between room temperature and moderate heating, or it needs to be controlled by water bath, oil bath and other temperature control means to maintain the temperature in a suitable range, such as 30 ° C to 80 ° C, depending on the specific reaction activity.
During the reaction, an appropriate amount of catalysts, such as some Lewis acid catalysts, can be added to accelerate the reaction process and improve the reaction rate and yield.
After the condensation reaction is completed and the preliminary product is obtained, it may need to be separated and purified. The column chromatography method can be used to select a suitable eluent with silica gel as the stationary phase, and the separation can be achieved according to the difference in the partition coefficient between the product and the impurities between the stationary phase and the mobile phase.
The separated product may require further functional group modification, such as the introduction of specific functional groups such as amino groups and carbonyl groups. For the introduction of amino groups, nucleophilic substitution reactions may be used, and amino-containing reagents are used to react with the product. The reaction conditions also need to be carefully regulated. Solvent, temperature, catalyst and other factors will affect the reaction effect.
