Reference of 22483-09-6,Some common heterocyclic compound, 22483-09-6, name is 2,2-Dimethoxyethanamine, molecular formula is C4H11NO2, 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.
General procedure: Benzaldehyde derivatives (1500 mg, 13.13 mmol) and Aminoacetaldehyde dimethyl acetal (19.70 mmol) were dissolved in 15 mL of methanol, NaBH(OAc)3 (19.70 mmol) was added at 0 C slowly in 3h. The reaction mixture was stirred at room temperature overnight and concentrated under reduced pressure. The residue was extracted with dicloromethane (DCM, 15 mL) three times, and the combined extracts were washed with 2N KOH, brine and dried over Na2SO4. The solution was filtered and added TEA (39.40 mmol) and TsCl (21.00 mmol) at 0C and stirred at room temperature for 5h. The resulting mixture was extracted with DCM (15 mL) three times. The combined organic layers were washed with brine, dried over Na2SO4, filtered and concentrated under reduced pressure. The resulting residue was purified by silica gel flash column chromatography (PE : EA = 5:1) to give the desired product.
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-Dimethoxyethanamine, its application will become more common.
