Reaction Steps

3-[2-(1-t-Butoxycarbonylpiperidin-4-yl)acetylamino]-N-(5-chloropyridin-2-yl)benzofuran-2-carboxamide (2.34 g) obtained in Example 212 is suspended in ethyl acetate (30 ml), and thereto is added 2.6N hydrogen chloride in ethyl acetate (30 ml), and the mixture is stirred at room temperature for 5 hours. The reaction solution is concentrated under reduced pressure, and to the resulting residue are added chloroform and an aqueous sodium hydrogen carbonate solution. The precipitates are collected by filtration to give the title compound (1.47 g).
