Reaction Conditions

Temperature70 °C

Reaction Steps

Zinc dust (3.0 g, 46 mmol) was added to 3-nitro-4-o-tolyl-pyridine (1.35 g, 6.3 mmol) in acetic acid (32 mL). The reaction mixture was heated to 70° C. for 90 min. After cooling to room temperature, solids were removed from the reaction mixture by filtration. Evaporation of volatiles in vacuo gave a solid that was triturated with toluene. Removal of solids by filtration followed by evaporation of volatiles in vacuo gave a heavy oil. The product 4-o-tolyl-pyridin-3-ylamine was isolated by flash chromatography on silica gel eluting with EtOAc to 5% CH3OH in EtOAc (1.0 g, 86%).
