실험 절차
A solution of 4-(methylsulfonyl)-2-nitro-1-vinylbenzene (Intermediate 121; 3.60 g; 15.8 mmol) in AcOH (100 mL) was treated with a solution of iron (15.9 g; 285 mmol) in AcOH (20 ml) and the reaction mixture was stirred at 60° C. for 1 h. EtOAc was added and the solution was filtered, the solvents removed under reduced pressure. The residue was taken up in EtOAc, washed with a sat. NaHCO3 solution in water, then with brine. The organic layer was dried, filtered and concentrated to give the title compound.
