Procedure

A solution of 3-bromophenylacetic acid (2.0 g, 9.3 mmol) and 4-dimethylamino pyridine (1.1 g, 9.3 mmol) in methanol (20 mL) was treated with N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (EDAC) (2.1 g, 11 mmol). Reaction stirred for 16 hours at room temperature. The reaction mixture was concentrated under reduced pressure. The residue was taken up in ethyl acetate and washed with water, saturated sodium bicarbonate, 1N phosphoric acid, and brine before drying over Na2SO4, filtering, and concentrating under reduced pressure to provide the title compound.
