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. 39753-81-6, name is Ethyl 2-(4-nitro-1H-pyrazol-1-yl)acetate, A new synthetic method of this compound is introduced below., Application In Synthesis of Ethyl 2-(4-nitro-1H-pyrazol-1-yl)acetate<\/a><\/p>\n

Under hydrogen (1 atm), to a solution of compound 33-b (1.0 g, 5 mmol) in methanol (10 mL) was added 10% Pd-C (0.1 g). The mixture was stirred at 25 C. for 12 hours, and then filtrated, the filtrate was concentrated under reduced pressure to give compound 33-a (760 mg, yield: 90%), which was used directly for the next step without purification. LC-MS (ESI): m\/z=170 [M+H]+.<\/p>\n

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.<\/p>\n
