실험 절차
To a solution of 4-nitrocatechol (310 mg, 2.0 mmol) in methanol (20 mL) is added hydrazine (200 μL) and a catalytic amount of Raney-Nickel (50 mg). The reaction mixture is left to stir at ambient temperature for 16 hours. The solution is then filtered over celite to remove Raney-Nickel and the filtrate evaporated to dryness. The 3,4-dihydroxyaniline thus produced is used as such for the next reaction.
