Procedure

To a solution of 5-(5-Nitro-pyridin-2-yloxy)-1-pyridin-3-yl-1H-indazole (0.79 mmol) in 10 mL of methanol was added 10 mL of ethyl acetate and 30 mg of platinum (IV) oxide. After shaking under 50 psi of H2 for 3 h, the mixture was filtered through a pad of Celite and concentrated in vacuo, affording 0.25 g of 5-(5-Amino-pyridin-2-yloxy)-1-pyridin-3-yl-1H-indazole
