Adding a certain compound to certain chemical reactions, such as: 929-06-6, 2-(2-Aminoethoxy)ethanol, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, COA of Formula: C4H11NO2, blongs to alcohols-buliding-blocks compound. COA of Formula: C4H11NO2
Step 1: Synthesis of tert-butyl N-[2-(2-hydroxyethoxy)ethyl] carbamate (AR)[0549] To a stirred solution of 2-(2-aminoethoxy)ethan-l-ol (AQ, 5.25 g, 49.94 mmol) in tetrahydrofuran (100 mL) was added aqueous solution of sodium bicarbonate (20% (w/w), 40 ml) and (Boc)20 (11.4 g, 52.23 mmol, added in several batches) at 0 C. The resulting mixture was then warmed up slowly to rt and stirred at rt for 5h. The bulk of organic solvent was removed under reduced pressure and the resulting residue was diluted with water (300 mL), extracted with of ethyl acetate (100 mL x 3). The organic layers were combined, washed with saturated aqueous solution of sodium chloride (20 mL x 2), dried over anhydrous sodium sulfate and then concentrated under reduced pressure to give AR (yield: 98%) as colorless oil.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,929-06-6, 2-(2-Aminoethoxy)ethanol, and friends who are interested can also refer to it.
