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. 5394-18-3, name is 2-(4-Bromobutyl)isoindoline-1,3-dione, A new synthetic method of this compound is introduced below., Recommanded Product: 5394-18-3
General procedure: A mixture of the corresponding secondary amine 3a-d [23] (5.5mmol), anhydrous K2CO3 (6mmol) and compounds 2a-d (5mmol) were added in CH3CN (20ml). The mixture was heated at 65C for 8-10h. The solvent was evaporated under reduced pressure. Then water (25mL) was added, and the mixture was extracted with dichloromethane (20mL×3). The combined organic phases were washed with saturated aqueous sodium chloride (30mL), dried over sodium sulfate, and filtered. The solvent was evaporated under vacuum. The residue was purified on a silica gel chromatography using mixtures of petroleum/acetone as eluent to obtain the oil products 4-7.
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.
