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. 875003-43-3, name is 7-Fluoro-1-methylindoline-2,3-dione, A new synthetic method of this compound is introduced below., Formula: C9H6FNO2
Step 2: Preparation of 7-fluoro-1-methyl-1,3-dihydro-indol-2-one 7-Fluoro-1-methyl-1H-indole-2,3-dione (Step 1, 1.05 g, 5.86 mmol) is heated with neat hydrazine hydrate (10 ml) at 130 C. for 1 hour. The mixture is cooled, diluted with ice water and extracted with ethyl acetate. The extract is washed with brine, dried (Na2SO4), and evaporated to give the title compound as a light yellow solid. HPLC r.t. 4.07 min; MS for C9H8FNO m/z 165.16 (M+H)+.
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.
