Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 29097-00-5, name is Methyl 3-amino-1H-pyrazole-4-carboxylate, A new synthetic method of this compound is introduced below., COA of Formula: C5H7N3O2
General procedure: A mixture of aminoazole 1c-e (1 mmol), acetoacetamide 2a,b,d (1 mmol), and aromatic aldehyde 3b,d-g (1 mmol) in 0.1 mL of DMF was heated to reflux for 10 min. After cooling acetone (10 mL) was added. The precipitate formed was filtered out to give the solid dihydropyrimidines 7a-e, which were washed with acetone and air dried.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
