To a stirred suspension of nitro compound 333 (32 mg, 0.57 mmol) in a mixture of MeOH (2 mL) and water (1 mL) were added iron powder (16 mg, 0.29 mmol) and NH4Cl (2.8 mg, 0.05 mmol). The reaction mixture was heated to reflux for 2.5 hrs, cooled to room temperature, diluted with ethyl acetate, filtered, and rinsed with AcOEt. The filtrate was successively washed with sat. ammonium chloride, sat. NaHCO3, water, dried over anhydrous MgSO4, filtered, and concentrated to afford title compound 334 (25 mg, 83% yield) as a pale yellow solid. MS (m/z): 521.0 and 523.0 (M+H)+.
