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. 6326-79-0, name is 6-Bromoisatin, A new synthetic method of this compound is introduced below., HPLC of Formula: C8H4BrNO2
The 1.15g (5mmol) 6- bromo-isatin was dissolved in 10mL DMF,1.03 g (7.5 mmol) of potassium carbonate was added with stirring.Then, 0.804 g (6.25 mmol) of dimethyl sulfate was added dropwise, and the mixture was reacted at room temperature for 4 hours, and the mixture was poured into 100 mL of ice water.The extract was extracted with ethyl acetate (60 mL×3), and the organic layer was evaporated.After concentrated to dryness, it was purified by silica gel column chromatography ( petroleum ether: ethyl acetate = 20:3)0.753 g of a red solid was obtained in a yield of 63%.
The synthetic route of 6326-79-0 has been constantly updated, and we look forward to future research findings.
