Procedure
A solution of 2-{[4-bromo-2-(methoxycarbonyl)thiophen-3-yl]oxy}propanoic acid (220 mg), 1H-benzotriazol-1-ol 1 ammonium salt (162 mg), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (205 mg) and DMF (4 mL) was stirred at room temperature for 1.5 hr. Water was poured into the reaction mixture, and the mixture was extracted with ethyl acetate. The extract was washed with water and saturated brine, and dried over magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was recrystallized from a mixed solvent of Et2O and hexane to give the title compound (195 mg, 89%) as colorless crystals.
