Reaction Steps

4-[3-{6-[3-Benzo[1,3]dioxol-5-yl-5-(piperazine-1-carbonyl)-phenoxy]-hexyl}-2-(2-carboxy-ethyl)-phenoxy]-butyric acid (0.29 mmol), acetic anhydride (1.2 eq.), triethylamine (3 eq.) were combined in dichloromethane (2 mL) and stirred overnight. Then the reaction mixture was diluted with ethyl acetate, washed with water and dried over anhydrous sodium sulfate. The organic extract was concentrated under reduced pressure and purified by reverse-phase HPLC to yield the title compound.
