1,2-Bis(2-aminophenoxy)ethyl-N,N,N',N'-acetic acid methyl ester 4
Compound 3 (2.44 g, 0.01 mol) was dissolved in MeCN (10 mL), then (i-Pr)2NEt (6 mL) and methyl bromoacetate (3 mL) were added to the mixture with stirring. The reaction mixture was refluxed for 24 h. After the reaction, the mixture was cooled down, poured into EtOAc (20 mL), and filtered to remove the generated white solid. The combined EtOAc filtrates were concentrated in vacuo to give an oily solid, then adding a little methanol, white solid was generated, filtered, air dried and recrystallized in MeOH to give white solid 4. Yield 87%;
