실험 절차

Raney/Ni (2.5 g) was added into a solution of 2-bromo-4-methoxy-6-nitrophenol (8.8 g, 35.5 mmol) in EtOAc (100 mL). The mixture was shaken in a Parr apparatus under hydrogen at 25 psi for 2.5 h. The reaction mixture was filtered through celite and concentrated under vacuum to give a gray solid (7.4 g, 96% yield; 95-97° C.); MS m/e 218 (M+H)+.
