5-Hydroxy-2-nitrobenzoic acid Use and Manufacturing
5-Chloro-2-nitrobenzoic acid (32.00 g, 0.159 mol), Dissolved in 15percent aqueous sodium hydroxide solution, The reaction was refluxed under N2 for 72h.After completion of the reaction, the pH of the solution was adjusted to 1.0, extracted with ethyl acetate, the combined ethyl acetate layers were dried over anhydrous sodium sulfate, The solvent was distilled off under reduced pressure to give 28.05 g of 5-hydroxy-2-nitrobenzoic acid in a yield of 96.5percent.Step 1: (0332) Potassium hydroxide aqueous solution (13.8 g, 248 mmol, 40 ml) was added into 5-chloro-2-nitrobenzoic acid 11-a (5 g, 24.8 mmol) and the mixture was stirred at reflux for 24 hours. The pH value of the reaction mixture was adjusted to 2 with concentrated hydrochloric acid under ice-cooling, the precipitated solid was filtered and dried to give 11-b as a white solid (4.1 g, yield: 90percent).General procedure: A suspension of 2-methylphenol(18.5 mmol, 1.0 eq) and Cu(NO
