Procedure
In 3 mL of dioxane, 40 mg (0.167 mmol) of 1-(4-nitrophenyl)-1H-imidazo[4,5-c]pyridine obtained in Step A of Example 1 was dissolved, and 40 mg of zinc powder and 1 mL of a saturated ammonium chloride aqueous solution were added thereto and the mixture solution was vigorously stirred at room temperature for one hour. The reaction solution was partitioned between ethyl acetate and water. The organic layer was washed with a sodium chloride solution, dried and then concentrated under reduced pressure to obtain a crude product of N-(4-imidazo[4,5-c]pyridine-1-ylphenyl)-hydroxylamine. The product was used in the next reaction without further purification.
