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. 19155-24-9, name is 3,3-Dimethylindolin-2-one, A new synthetic method of this compound is introduced below., Quality Control of 3,3-Dimethylindolin-2-one
2c. 3,3-dimethylindoline:; To a 1M of LAH (30 mL) in THF was added 2b (630 mg, 3.88 mmol) in portion. The reaction mixture was stirred at rt for 2 h, then refluxed for 1 h. The reaction mixture was quench with 1 part of H2O (10-mL), one part of 15percent NaOH (5 mL) and another part of H2O (5 mL). The aqueous layer was extracted with EtOAc. The EtOAc layer was dried over Na2SO4 and filtered. The solvent was evaporated under reduced pressure to afford 2c (320 mg, 56percent) as an oil. MS (ES) m/z 150 [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.
