Reaction Steps

To a stirred mixture of 2-(2-methoxyphenyl)-3-nitropyridine (34.3 mg, 0.15 mmol) in EtOAc (5.0 mL) was added tin(II) chloride dihydrate (0.17 g, 0.76 mmol) in portions. Upon complete addition of the reducing agent, the mixture was carefully heated to 65° C. After 19 h, the reaction was cooled to rt and diluted with EtOAc, then washed with 1M NaOH (10 mL), water (10 mL), and brine (10 mL). After drying over anhydrous sodium sulfate and filtration, the organic solvent was removed under reduced pressure. The residue was identified as mostly 2-(2-Methoxyphenyl)-3-pyridinamine. Mass Spectrum (pos.) m/e: 201.1 (M+1).
