Related Products of 111-95-5,Some common heterocyclic compound, 111-95-5, name is Bis(2-methoxyethyl)amine, molecular formula is C6H15NO2, 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.
A suspension of l-methyl-5-(2-phenyl-[l,2,4]triazolo[l,5-a]pyridin-7-ylcarbamoyl)-lH- pyrazole-4-carboxylic acid with 1 eq. lithium chloride (80 mg, 0.198 mmol), bis(2- methoxyethyl) amine (87 ul, 0.59 mmole), diisopropylethylamine (104 ul, 0.59 mmol) and propylphosphonic anhydride (50 % in ethyl acetate, 291 ul, 0.494 mmol) in tetrahydrofurane (4 ml) is stirred for 2.5 hours at 70 C giving after 20 min a light yellow solution. The cooled solution is diluted with ethyl acetate, washed once with sat. aqueous sodium carbonate solution, once with IN aqueous hydrochloric acid, once with brine, dried with magnesium sulfate and the solvent is evaporated to dryness affording N4,N4-bis(2-methoxyethyl)-l-methyl-N5-(2-phenyl- [l,2,4]triazolo[l,5-a]pyridin-7-yl)-lH-pyrazole-4,5-dicarboxamide (80 mg, 84.8%) as a colorless waxy solid. MS: m/z= 478.2 (M+H+).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route Bis(2-methoxyethyl)amine, its application will become more common.
