Versuchsvorschrift

Methyl bromoacetate (2.1 g) was added to a stirred mixture of N-[2-(4-chlorophenoxy)ethyl]-3-(imidazol-1-yl)propylamine (3.87 g) and anhydrous potassium carbonate (5.73 g) in dry acetone (180 ml). The mixture was stirred and boiled under reflux for 7 hours, then left to stand at ambient temperature for 18 hours then hot filtered. The filtrate was evaporated to dryness and the residue was purified by chromatography on silica using ethyl acetate/triethylamine, 9 to 1 as the mobile phase. The product was obtained as an oil which was dissolved in ether, and extracted into 5M hydrochloric acid. The acid extracts were basified with 5M sodium hydroxide solution and the product extracted into ether to give methyl N-[2-(4-chlorophenoxy)ethyl]-N-[3-(imidazol-1-yl)propyl]glycinate as an oil.
