The 1H-indole-3-carboxylic acid[6-(2-methyl-pyridine-3-yloxy)-pyridine-3-yl]-amide (0.2 g, 0.58 mmol) in Example 6 was dissolved in dichloromethane (10 ml), and Boc2O (0.15 g, 0.7 mmol) and triethylamine (0.12 g, 1.16 mmol) were added to the solution. The reaction solution was stirred at room temperature for 2 hours, and then the product was washed, filtered, and dried to obtain tert-butyl-3-(6-(2-methylpyridine-3-yloxy)pyridine-3-ylcarbamoyl)-1H-indole-1-carboxylate (0.27 g, 0.52 mmol). The tert-butyl-3-(6-(2-methylpyridine-3-yloxy)pyridine-3-ylcarbamoyl)-1H-indole-1-carboxylate (0.27 g, 0.52 mmol) was dissolved in THF (10 ml), and NaH (21 mg, 0.54 mmol) and methyl iodide (0.95 g, 0.67 mmol) were added to the solution. The reaction solution was stirred at room temperature for 5 hours, and then the product was washed and filtered to yield tert-butyl-3-(methyl(6-(2-methylpyridine-3-yloxy)pyridine-3-yl)carbamoyl)-1H-indole-1-carboxylate (40 mg, 0.087 mmol) by chromatography (methanol:dichloromethane=1:20).
