Reaction Steps

A mixture of 2-(3,4-dichlorophenyl)acetic acid (1 g, 4.9 mmol), N,O-dimethylhydroxylamine hydrochloride (480 mg, 4.9 mmol), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (940 mg, 4.9 mmol), hydroxybenzotriazole (660 mg, 4.9 mmol), and triethylamine (2.5 g, 25 mmol) in dichloromethane (30 mL) was stirred at room temperature overnight. The reaction mixture was diluted with water (30 mL), and extracted with EtOAc (30 mL×3). The combined organic layers were dried over Na2SO4, concentrated in vacuo, and purified by column chromatography (PE:EtOAc=10:1) to afford 2-(3,4-dichlorophenyl)-N-methoxy-N-methylacetamide (880 mg, yield 72.7%).
