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. 870-24-6, name is 2-Chloroethanamine hydrochloride, A new synthetic method of this compound is introduced below., SDS of cas: 870-24-6
Step-I: 2-(2-Methyl-1H-pyrrol-1-yl)ethanamineSodium hydroxide anhydrous (9.87 g, 0.246 mol, 4.0 eq.) and TBAHS (0.838 g, 0.002 mol, 0.04 eq.) were added to a solution of 2-methyl-1 H-pyrrole (5.0 g, 0.061 mol, 1.0 eq.) in acetonitrile (180 ml) at 0 C and the mixture was stirred at RT for 1 h. 2-Chloroethylamine hydrochloride (8.59 g, 0.074 mol, 1.2 eq.) was added to the reaction mixture and it was then heated at reflux for 16 h. The reaction mixture was cooled to RT, filtered through celite and washed with 10% MeOH/DCM (200 ml). The filtrate was concentrated under reduced pressure to give the crude product which was used in the next step without further purification.Yield: 100 %, crude (7.6 g, 0.061 mol)
The synthetic route of 870-24-6 has been constantly updated, and we look forward to future research findings.
