Hydrochloric Acid → 3-Ethoxy-4-nitrobenzoic acid

Participants

Reaction Steps

3-fluoro-4-nitrobenzoic acid (Apollo Scientific; 15 g, 81 mmol) and potassium hydroxide (10.5 g, 186.3 mmol) were stirred together in ethanol (150 mL) at ambient temperature. The reaction mixture was slowly heating to reflux over 10 minutes. The reaction refluxed vigorously and a solid precipitate formed. The reaction was cooled, diluted with water (100 mL) and acidified with 2N HCl to give a precipitate which was filtered, washed with water and air dried to yield the title compound as a pale brown solid (16.88 g, 99%)
