How is 2-[2-(2-Aminoethoxy)ethoxy]ethanol (CAS: 6338-55-2) typically synthesized?

2-[2-(2-Aminoethoxy)ethoxy]ethanol is typically synthesized through a multi-step process involving the reaction of ethylene glycol with 2-aminoethanol followed by further alkoxylations. The specific conditions, such as temperature and pressure, and the use of catalysts like sulfuric acid are crucial for obtaining high yields and selectivity.
