Reaction Steps
2-(4-Nitrophenyl)pyridine (1.10 g) and 10% Pd/C (300 mg) were dissolved suspended in 80 mL of an 8:1 solution of 30 mL of THF and 10 mL of ethanol under an atmosphere of dry N2. To this solution was added 1.0 mL of anhydrous hydrazine. The reaction mixture was stirred at room temperature overnight and then filtered. The filtrate was concentrated under vacuum. The residue was partitioned between dichloromethane and water and the organic layer was washed with brine, dried over MgSO4, filtered and concentrated under vacuum. The residue was purified via silica gel chromatography to give 653.3 mg of 4-(pyridin-2-yl)benzenamine.
