Benzoic acid, 3-amino-5-hydroxy-, hydrochloride (1:1) Use and Manufacturing

Step 1:Step 2: 3-tert-butoxycarbonylamino-5-hydroxy-benzoic acid 3-Amino-5-hydroxy-benzoic acid hydrochloride (40.0 g) prepared in Step 1, sodium hydroxide (25.3 g), and sodium hydrogen carbonate (21.3 g) were dissolved in distilled water (300.0 mL). (BOC)2O (46.0 g) and dioxane (200.0 mL) were added to the solution, which was then stirred at room temperature for 12 hours. The reaction mixture was concentrated, acidified with a 2 N hydrochloric acid solution, and then extracted with ethyl acetate three times. The organic layer was dried on anhydrous magnesium sulfate, and then concentrated under reduced pressure to obtain 33.0 g of the titled compound in the form of white foam (Yield: 62.0%). 1H-NMR (d6-DMSO) delta 7.34 (s, 1H), 6.95 (s, 1H), 6.72 (s, 1H), 1.24 (s, 9H)
