Procedure

A mixture of 200 mg of ethyl 4-amino-2-[p-(4-phenylbutoxy)benzamido]phenoxyacetate hydrochloride, 70.4 mg of ethyl bromoacetate, 114 mg of anhydrous potassium carbonate and 5 ml of N,N-dimethylformamide was stirred at room temperature overnight. To the reaction mixture was added 30 ml of ethyl acetate. After washing with water, the system was dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was applied to silica gel column chromatography and eluted with a toluene-ethyl acetate (4:1) mixture to obtain 140 mg of ethyl 4-(ethoxycarbonylmethylamino)-2-[p-(4-phenylbutoxy)benzamido]phenoxyacetate.
