Acetic Acid → 5-Ethyl-2-[(6-fluoropyridin-2-yl)oxy]phenyl acetate

Participants

Reaction Steps

To a solution of 5-Ethyl-2-(6-fluoro-pyridin-2-yloxy)-phenol (20 mg; 0.09 mmol), under argon, in dimethylformamide (2 mL), cooled to 0° C., was added triethylamine (36 μL; 0.26 mmol) and acetic acid (10 μL; 0.18 mmol). The reaction mixture was allowed to stir overnight, with gradual warming to room temperature. The reaction was concentrated, diluted with saturated NaHCO3 (5 mL) and extracted with ethyl acetate (3*3 mL). Combined organic phases were dried over Na2SO4, concentrated in vacuo, the title compound (8 mg; 34%) was obtained as clear oil, after purification on neutral alumina gel (cyclohexane/ethyl acetate: 9/1).
