Definition

ChEBI: 1-(2-(2-Hydroxyethoxy)ethyl)piperazine is a N-alkylpiperazine.

Synthesis

166388-52-9

13349-82-1

The general procedure for the synthesis of 1-[2-(2-hydroxyethoxy)ethyl]piperazine from the compound (CAS:166388-52-9) was as follows: 54.2 g of compound 3 was dissolved in 300 mL of dichloromethane, followed by the addition of 26 g of trifluoroacetic acid. The reaction mixture was stirred at room temperature for 2 h. The progress of the reaction was monitored by thin layer chromatography (TLC) until the reaction was complete. After completion of the reaction, 1 N NaOH aqueous solution was added and stirring was continued for 30 minutes. The reaction mixture was left to partition and the organic phase was separated. The organic phase was dried over anhydrous sodium sulfate and subsequently concentrated under reduced pressure to give 32.6 g of a colorless liquid product, i.e., 1-[2-(2-hydroxyethoxy)ethyl]piperazine. The yield was 95%.
