Reaction Steps
To a suspension of 3-fluorobenzoic acid (140 mg, 1 mmol) and N,O-dimethylhydroxylamine hydrochloride (107 mg, 1.1 mmol) in dichloromethane (2.5 mL) was added 1-[3-(dimethylamino)propyl]-3-ethylcarbodiimide hydrochloride (EDC) (211 mg, 1.1 mmol) and the mixture stirred at room temperature for 75 h. The solvents were removed under reduced pressure and the residue chromatographed using ethyl acetate-hexane (4:6) to separate the pure product (130 mg, 71%).
