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. 17417-09-3, name is 2-Fluoro-5-nitrobenzonitrile, A new synthetic method of this compound is introduced below., Quality Control of 2-Fluoro-5-nitrobenzonitrile
A solution of 2-fluoro-5-nitro-bezonitrile (300 mg, 1.81 mmol) and methyl hydrazine (170 mg, 3.62 mmol) in dioxane (10 mL) was stirred at 80 C. for 2 h. The reaction mixture was cooled and partitioned between 1N aqueous HCl and EtOAc. The organic layer was washed with water dried over Na2SO4 filtered and concentrated to the desired product 5-nitro-1-methyl-1H-indazol-3-ylamine (280 mg, 80%). HRMS for C8H8N4O2 (M+H) calcd: 193.0720. Found:193.0720
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.
