실험 절차
5-Nitrobenzo[d]isothiazole (305 mg, 1.69 mmol), 5% AcOH (aq.) (12 mL) and EtOAc (12 mL) at 65° C. was treated with iron powder (325 mesh, 473 mg) and stirred rapidly for 1 h. The mixture was cooled to ambient temperature, diluted with water and EtOAc and filtered through dicalite. The organic layer was separated and the aqueous layer extracted with further EtOAc. The combined organic extracts were washed with brine, dried (MgSO4) and concentrated in vacuo to give the title compound as a yellow solid (220 mg, 85%).
