Hydrochloric Acid → 2-Nitro-4-phenoxyaniline

Participants

Reaction Steps

N-(2-nitro-4-phenoxy-phenyl)acetamide (0.67 g, 2.33 mmol) prepared in Step B was dissolved in methanol (5 mL), 6.0N sodium hydroxide (1.5 mL) was added thereto, and the mixture was stirred for 18 h at room temperature. After completion of the reaction, 6.0N aqueous hydrochloric acid solution (1.3 mL) and ammonium chloride solution (100 mL) were added thereto. The reaction mixture was extracted with ethyl acetate, dried over magnesium sulfate, and recrystallized from dichloromethane and hexane to give the title compound (521 mg, 2.12 mmol),
