Participants

Reaction Steps

To a solution of 2-(3-bromophenyl)acetic acid (4.4 g, 20.56 mmol) in N,N-dimethylformamide (125 ml) was successively added N,O-dimethylhydroxyamine (4.5 g, 46.26 mmol), triethylamine (10 ml), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (8.9 g, 46.26 mmol) and 1-hydroxybenzotriazole (6.24 g, 46.26 mmol). The reaction mixture was stirred at room temperature overnight, and partitioned between ethyl acetate and brine. The organic phase was washed with brine, and concentrated. The residue was purified by flash chromatography on silica gel (50% ethyl acetate in hexane) to provide the title compound. MS (DCI/NH3) m/z 258 (M+H)+.
