Reaction Steps

Potassium carbonate and benzyl bromoacetate were added to DMF solution of ethyl (4-aminophenoxy)acetate and stirred under heating. After adding water and ethyl acetate to the reaction mixture, the organic layer was separated, washed and dried, and then the solvent was evaporated under a reduced pressure. Dichloromethane solution of the thus obtained crude product was mixed with TEA, 4-fluorobenzoyl chloride was added dropwise thereto under ice-cooling and then the reaction solution was stirred. After adding 1 M hydrochloric acid to the reaction solution, the organic layer was separated, washed and dried, and then the solvent was evaporated under a reduced pressure. By purifying the thus obtained crude product by SCG, ethyl {4-[benzyloxycarbonylmethyl-(4-fluorobenzoyl)amino]phenoxy}acetate (colorless oil) was obtained.
