Reference of 31576-51-9,Some common heterocyclic compound, 31576-51-9, name is 2-(2-Methoxyethoxy)ethanamine, molecular formula is C5H13NO2, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
To a solution of 4-thioxo-l, 3-thiazolidin-2-one (2.24 g) in ethanol (20 mL) was added 2- (2-methoxyethoxy) ethanamine (2.5 g), and the mixture was stirred at room temperature for 5 hr. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography(ethyl acetate) to give the title compound (3.1 g) .XH NMR (300 MHz , CDC13) delta 3.43 (3H, s) , 3.48-3.63 (2H, m) , 3.63-3.83 (6H, m) , 4.13 (2H, s) , 6.83 (1H, brs) .MS (ESI+) : [M+H]+ 219.1.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 2-(2-Methoxyethoxy)ethanamine, its application will become more common.
