These common heterocyclic compound, 106984-09-2, name is tert-Butyl (2-(2-(2-(2-hydroxyethoxy)ethoxy)ethoxy)ethyl)carbamate, its 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. 106984-09-2
To a stirred solution of tert-butyl (2-(2-(2-(2-hydroxyethoxy)ethoxy)ethoxy)ethyl)carbamate (0.38 g, 1.29 mmol) and 2-bromoacetic acid (0.54 g, 3.8 mmol) in toluene:THF (1:1, 4 mL) was added NaOH (0.31 g, 7.7 mmol) at 45 C. The resulting reaction mixture stirred at 45 C. for 16 h. The reaction mixture was then evaporated, water (10 mL) was added and aqueous layer was acidified with 1 N HCl solution. The resulting mixture was extracted using DCM (3¡Á50 mL) and the combined organic layer was dried over anhydrous sodium sulfate and filtered. The filtrate was evaporated under reduced pressure to give 2,2-dimethyl-4-oxo-3,8,11,14,17-pentaoxa-5-azanonadecan-19-oic acid as a colorless oil (0.24 g, 53%). LC-MS (ESI+) m/z 351.4 (M+H)+.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 106984-09-2.
