反応手順
To a solution of 1 g 2-(2-Methoxy-ethoxy)-6-nitro-phenylamine in 10 mL ethyl acetate and 3 mL ethanol, 4.4 g SnCl2 dihydrate were added and the reaction mixture was heated to reflux for 6 h. Then, after cooling 50 mL 2 M NaOH were added and the inorganic precipitate was filtered and washed extensivley with ethyl acetate. The filtrate was extracted with exthyl acetate (3×100 ml), the combined organic layers were dried over MgSO4, and the solvents were removed under reduced pressure. The remaining product was pure enough for the next reaction step.
