Reaction Steps

Trans-4-amino-3-[4-(2-oxopyrrolidin-1-yl)cyclohexylcarbonylamino]-N-(5-chloropyridin-2-yl)benzofuran-2-carboxamide (27 mg) obtained in Example 426 is dissolved in pyridine (2 ml), and thereto is added methanesulfonyl chloride (7 μl) under ice-cooling. The mixture is stirred at room temperature overnight, and thereto are further added pyridine (3 ml) and methanesulfonyl chloride (500 μl) under ice-cooling. The mixture is stirred at room temperature for 6 hours. Water is added to the reaction solution, and the mixture is extracted with chloroform. The solvent is evaporated under reduced pressure, and the resulting residue is purified by silica gel column chromatography (eluent: chloroform, then chloroform/methanol=9/1) to give the title compound (21.2 mg).
