N-(2,6-dimethyl-3-nitrophenyl)acetamide → N-(3-amino-2,6-dimethylphenyl)acetamide

참여 물질

반응 단계

N-(2,6-dimethyl-3-nitro-phenyl)acetamide (12 g, 58 mmol, 1.0 eq) was dissolved in a mixture of MeOH (60 mL), EtOH (30 mL) and acetic acid (60 mL). Pd/C (1.6 g, 10%) was added and the reaction stirred at room temperature under H2 for 36 h. The catalyst was removed by filtration through celite and the filtrate collected. Water was added and the pH adjusted to pH 8 by addition of aqueous NaHCO3. The solution was concentrated in vacuo to remove methanol and ethanol. The aqueous layer was extracted with EtOAc and the combined organic extracts were dried (Na2SO4) filtered and evaporated in vacuo. The crude product was purified by column chromatography (EtOAc:petroleum ether, 1:10 to 1:1) to give the title compound as a yellow solid (2 g, 19%).
