A new synthetic route of Methyl 1-Methylpyrazole-3-carboxylate

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.

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. 17827-61-1, name is Methyl 1-Methylpyrazole-3-carboxylate, A new synthetic method of this compound is introduced below., Recommanded Product: 17827-61-1

Step 2: To a solution of step 1 intermediate (7.0 g, 50 mmol) in a mixture of THF (20 mL) and MeOH (20 mL) was added a solution of LiOH H20 (4.2 g, 100 mmol) in water (20 mL) at 0C. The RM was stirred at rt for 3 h. The RM was concentrated and subsequently diluted with water. The aqueous layer was acidified with sat. NaHS04 solution up to pH~4-5 and extracted with EtOAc. The combined organic layers were dried and concentrated under reduced pressure to yield the desired product (6.2 g, 98%). LC-MS (Method 3): m/z [M+H]+ = 127.2 (MW calc. 126.11); R, = 0.44 min.
