Ammonium Chloride → 2-Methoxy-4-(2-methylsulfanyl-ethoxy)-phenylamine

Participants

Reaction Steps

Step B A suspension of 2-methoxy-4-(2-methylsulfanyl-ethoxy)-1-nitro-benzene (0.25 g, 1.0 mmol) in methanol (8 mL) was added an aqueous solution (4 mL) of NH4Cl (0.55 g, 10 mmol), followed by activated Zinc (Aldrich, 0.67 g, 10 mmol). The reaction mixture was stirred at room temperature for 0.5 h. The mixture was filtered through a short pad of celite. The mixture was concentrated. The residue was partitioned between ethyl acetate and water. The organic layer was separated, and aqueous layer was extracted with ethyl acetate. The combined organic extract was washed with water, brine, dried over MgSO4, and concentrated to give 2-methoxy-4-(2-methylsulfanyl-ethoxy)-phenylamine as a brown oil (0.2 g, 91%).
