Route of Synthesis (ROS)

Route of Synthesis (ROS) of ethoxy]acetic acid CAS# 166108-71-0

ConditionsYieldWith anhydrous sodium carbonate In tetrahydrofuran at 15 - 20℃; for 3h;Experimental ProcedureCompound A3 (0.2g, 1.23mmol), 2mL of tetrahydrofuran, 2mL of water and sodium carbonate (0.2g, 1.84mmol) were added to the reaction kettle, the reaction temperature was maintained at 15-20°C, and fluorene methoxycarbonyl succinimide was added. (abbreviated as Fmoc-Osu, 0.4 g, 1.23 mmol) to carry out acylation reaction, after 3 hours of reaction, spot plate to confirm the end point of the reaction, then add ethyl acetate to the reaction solution, adjust pH=2-3 with hydrochloric acid, stand for fractionation The organic phase was washed three times with saturated brine, dried over sodium sulfate, and concentrated to obtain Fmoc-AEEA (0.43 g, yield 91%, purity 99.8%).The purity of Fmoc-AEEA synthesized in this example is 99.8%, and the total yield is 88%×91%×93%×91%=67.78%.91%With Sodium hydrogenocarbonate In ethanol; lithium hydroxide monohydrate for 6h; pH=9;Experimental Procedure Add sodium bicarbonate solid to adjust the product pH of step d to be about 9, then add 140mL of water, 140ml of ethanol, add 42.5g of Fmoc-osu in batches, react 6h after TLC monitoring, after the completion of the reaction; concentrate most of the ethanol under reduced pressure , the pH was adjusted to 2 with hydrochloric acid, crystal seeds were added for crystallization, the solid was precipitated and the crystallization continued for 2 h, filtered and dried to obtain 41.6 g of a white solid, namely ethoxy base]acetic acid.Result detection: the obtained ethoxy]acetic acid has a purity of 99.6% and a yield of 63.2%.63.2%With potassium carbonate In lithium hydroxide monohydrate for 16h;
