Reaction Steps

In a volumetric flask N,O-dimethylhydroxylamine hydrochloride (25.54 g, 261.8 mmol) and CH2Cl2 (443 mL) were introduced under argon atmosphere at 0° C. 4-Fluorobenzoyl chloride (34.59 g, 218.2 mmol) was added followed by the slow addition of triethylamine (48.13 g, 475.6 mmol). The reaction was stirred for 30 min at 5° C. and allowed to reach room temperature. It was washed with 5% aqueous citric acid (180 mL) and with 5% aqueous NaHCO3 (180 mL). The aqueous phase was extracted with CH2Cl2. The organic phase was dried over Na2SO4 and concentrated to dryness, to afford 20.23 g of the desired compound (yield: 88%).
