As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 6338-55-2, name is 2-(2-(2-Aminoethoxy)ethoxy)ethanol, molecular formula is C6H15NO3, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below. Formula: C6H15NO3
To a stirring mixture of 2-[2-(2-aminoethoxy)ethoxy]ethanol (S108A, 25.0 g, 167 mmol) and N-methyl morpholine (21.0 mL, 191 mmol) in dioxane (100 mL) was added dropwise a solution of Fmoc-OSu (62.2 g, 184 mmol) in dioxane (50 mL). After stirring overnight, the reaction was concentrated in vacuo to afford a light yellow oil. The crude was re-dissolved in EtOAc and washed with sat. NaHCO3 (aq.) and brine. The organic layer was removed in vacuo to afford an oil, which was purified by SiO2 chromatography to provide the FmocNH-PEG2-OH (S108, 55 g, 88% yield). ESI+ m/z calcd 371.4, found 372.2 [M+H]+.
With the rapid development of chemical substances, we look forward to future research findings about 6338-55-2.
