2-[2-(2-AMINOETHOXY)ETHOXY]ETHANOL

6338-55-2

The general procedure for the synthesis of 2-[2-(2-aminoethoxy)ethoxy]ethanol from 2-(2-(2-azidoethoxy)ethoxy)ethanol was as follows: 2-(2-(2-azidoethoxy)ethoxy)ethanol (0.7 g, 3.99 mmol) was dissolved in methanol (9 mL), followed by addition of a palladium/activated carbon catalyst (0.196 g) under stirring conditions . The reaction flask was subjected to three evacuation/hydrogen flush cycles to establish a hydrogen atmosphere. The progress of the reaction was monitored by thin layer chromatography (TLC), which showed the completion of the reaction after 8 hours. The reaction mixture was filtered through diatomaceous earth to remove the palladium/activated carbon catalyst. The filtrate was concentrated under reduced pressure to afford 2-[2-(2-aminoethoxy)ethoxy]ethanol as a colorless oil (0.6 g, quantitative yield).
