SYNTHESIS OF 2-(2-AMINOETHOXY) ETHANOL
A method for synthesizing 2-(2-aminoethoxy) ethanol, including the steps of producing 2-(2-phthalimidoethoxy) ethanol by reacting 5-tosyloxy-3-oxapentanol with potassium phthalate and converting the 2-(2-phthalimidoethoxy) ethanol to the 2-(2-aminoethoxy) ethanol by reacting the 2-(2-phthalimidoethoxy) ethanol with hydrazine monohydrate. Reacting the 2-(2-phthalimidoethoxy) ethanol with the hydrazine monohydrate may include forming a final mixture by adding the hydrazine monohydrate to a solution of 2-(2-phthalimidoethoxy) ethanol, refluxing the final mixture in a nitrogen atmosphere, extracting a second organic phase containing the 2-(2-aminoethoxy) ethanol from the final mixture using a second portion of chloroform, and purifying the 2-(2-aminoethoxy) ethanol from the second organic phase.
