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., Recommanded Product: 6326-79-0
Step 1: Synthesis of Intermediate 1-12.1 To R27 (25.0 g, 111 mmol) in acetonitrile (750 mL) is added Mel (15 niL, 241 mmol) and K2C03 (60.0 g, 434 mmol) and the reaction mixture is stirred at 60 C for 2 h. The reaction mixture is filtered and concentrated. Water and ethyl acetate are added to the residue. The organic layer is extracted twice with water, dried over MgS04 and concentrated. Yield 56%, m/z 240/242 [M+H]+, rt 0.48 min, LC-MS Method X001 004.
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.
