YieldReaction ConditionsOperation in experiment
76% In ethanol; at 20℃; for 0.5h; Under ice-cooling, <strong>[769-54-0]3-fluoro-4-nitropyridine 1-oxide</strong> (12 g, 76 mmol) and the mixed suspension of ethanol (300 mL), 20% sodium ethoxide ethanol solution (29g, 86mmol) was added to the . The temperature was raised to room temperature, and reacted under the same temperature for 30 minutes. The ethanol was evaporated under reduced pressure, and the residue water (200 mL) was added to, and the mixture was stirred for 15 minutes at room temperature. The solid was collected by filtration, washed with water and dried under reduced pressure to give 3-ethoxy-4-nitropyridine 1-oxide (11 g, 76% yield).

The solid was collected by filtration, washed with water, dried under reduced pressure to obtain the desired product (11 g, 76% yield).
76% In ethanol; for 0.5h;Cooling with ice; The sodiumethoxide ethanol solution (29 g, 86 mmol) was added to the mixed suspensionof <strong>[769-54-0]3-fluoro-4-nitropyridine-1-oxide</strong> (12 g, 76 mmol) and ethanol (300 mL) 20% under icecooling. It reacted for 30 minutes at waiting and a room temperature until the reaction solutionbecame a room temperature. Ethanol was distilled off under decompression, water (200 mL)was added to residue, and it agitated for 15 minutes at the room temperature. The solid wasdried under filtering, rinsing, and decompression and 3ethoxy4nitropyridine 1oxide (11 g,76% of yield) was obtained.
