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. 116008-52-7, name is 4-Amino-1H-pyrazole-3-carboxylic acid, A new synthetic method of this compound is introduced below., COA of Formula: C4H5N3O2
EXAMPLE 125 Trans-3-(naphth-2-yl)-but-2-enoic acid-N-(3-carboxy-1H-pyrazol-4-yl)-amide Prepared analogously to Example 31 from trans-3-(naphth-2-yl)-but-2-enoic acid chloride and 4-amino-1H-pyrazol-3-carboxylic acid in dimethylformamide with the addition of pyridine.
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.
