To prepare 5- (2-furyl) -1- [ (p-methoxy-3-pyridyl) carbonyl] -1H-pyrazole-3-carboxylate ethyl ester, the following ancient method can be used.
Take the furan first and introduce the 2-furan group in an appropriate way. This step requires mild reaction conditions to prevent damage to the furan ring. Common electrophilic substitution reactions can be used. Halogenated furans are used as raw materials and combined with corresponding reagents under the action of catalysts to obtain intermediates containing 2-furan groups.
Then, prepare the (p-methoxy-3-pyridyl) part. Starting from pyridine, through methoxylation, the methoxy group is introduced at the appropriate check point of the pyridine ring, and nucleophilic substitution or other adaptation methods can be selected. Then the methoxy-containing pyridine intermediate is connected to a carbonyl group through a specific reaction to achieve the (p-methoxy-3-pyridyl) carbonyl structure.
As for the construction of the 1H-pyrazole-3-formate ethyl ester part, it can be obtained from simple raw materials, such as nitrogen-containing heterocyclic precursors, through cyclization. For example, with an appropriate nitrogen-containing and carbonyl-containing compound, under the catalysis of a base or acid, a series of condensation and cyclization reactions form a pyrazole ring, and ethyl formate is introduced at the 3rd position.
Finally, the above three parts are cleverly spliced. The activity of carbonyl can be used to connect 5- (2-furyl), 1- [ (p-methoxy-3-pyridyl) carbonyl] with 1H-pyrazole-3-carboxylate ethyl ester through condensation reactions, etc., to obtain the target product. In this process, it is necessary to fine-tune the reaction conditions, such as temperature, pH, and the proportion of reactants, to ensure the smooth progress of the reaction and improve the purity and yield of the product. After each step of the reaction, it should be purified by ancient methods, such as extraction, recrystallization, etc., to remove impurities and improve quality to obtain a good product.
