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. 25369-33-9, name is 7-Chloroindolin-2-one, A new synthetic method of this compound is introduced below., name: 7-Chloroindolin-2-one
To a coo?ed (0 C) soution of 7-choroindohn-2-one (1 g, 6.0 mmo) in TFA (11 mL) was added Nbromosuccinimide (1 g, 6.0 mmo) portion wise and stirred the mixture at same temperature for 6 h. Concentrated TFA in vacuo with DCM (25 mL) and then with EtOAc. The crude product was triturated with ethano to provide the tiDe compound as a white soid (861 mg, 58% yie?d). MS (ES):mass cacd, for C6H5BrCNO, 244.9; m/z found, 246.0 [M+H]. 1H NMR (500 MHz, DMSO d6) oe 10.92 (5, 1 H), 7.52 7.48 (m, I H), 7.38 (d, J = 1.2 Hz, I H), 3.62 (s, 2H).
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.
