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. 110860-60-1, name is Methyl 5-amino-1-methyl-1H-pyrazole-4-carboxylate, A new synthetic method of this compound is introduced below., Recommanded Product: 110860-60-1
50.0 parts of a compound represented by the above formula (1) was added to 220 parts of isopropanol and heated to 45 C. to be completely dissolved. To this solution was added dropwise 27.0 parts of concentrated hydrochloric acid over 20 minutes.After the addition is complete, the reaction solution is cooled to 5 C.The resulting powder was filtered off. Is it enough with isopropanolAfter washing, it was dried at 50 C. for 3 hours to obtain 50.0 parts (yield 81.0%) of the hydrochloride of the compound represented by the formula (1).
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.
