Hydroxy-PEG2-methylamine

反应条件: temp:60.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 2-[2-(2-Chloro-ethoxy)-ethoxy]-ethanol (2.00 mL, 13.8 mmol) was dissolved in ethanol (14.0 mL). A solution of methylamine in methanol (40%, 14.0 mL, 138 mmol) and sodium iodide (103 mg, 0.67 mmol) were added, and the mixture was stirred at 60° C. for 18 hours and then stirred at 75° C. for seven hours in a nitrogen atmosphere. The reaction solution was concentrated under reduced pressure to give 2-[2-(2-methylamino-ethoxy)-ethoxy]-ethanol as a crude product. stirred at 75° C. for seven hours in a nitrogen atmosphere The reaction solution was concentrated under reduced pressure
