Reaction Steps

3-[(Piperidin-4-yl)carbonylamino]-N-(5-chloropyridin-2-yl)benzofuran-2-carboxamide (100 mg) obtained in Example 228 is dissolved in N,N-dimethylformamide (3 ml), and thereto are added successively nicotinic acid (34 mg), 1-hydroxybenzotriazole (37 mg) and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (53 mg), and the mixture is stirred at room temperature for 4 hours. To the reaction solution are poured a saturated aqueous sodium hydrogen carbonate solution and water, and the precipitates are collected by filtration, washed with chloroform, and dried to give 3-[1-((pyridin-3-yl)carbonyl)piperidin-4-ylcarbonylamino]-N-(5-chloropyridin-2-yl)benzofuran-2-carboxamide (103 mg). This product is treated with hydrogen chloride in dioxane to give the title compound (115 mg).
