Procedure

Trans-3-[4-(isopropylamino)cyclohexylcarbonylamino]-N-(5-chloropyridin-2-yl)benzofuran-2-carboxamide (100 mg) obtained in Example 310 and triethylamine (61 μl) is dissolved in chloroform (5 ml), and thereto is added acetyl chloride (24 μl). The mixture is stirred at room temperature for one hour, and thereto is poured a saturated aqueous sodium hydrogen carbonate solution, and the mixture is extracted with chloroform. The organic layer is washed successively with water and a saturated brine, dried over sodium sulfate, and the solvent is evaporated under reduced pressure. The resulting residue is purified by silica gel column chromatography (eluent: n-hexane/ethyl acetate=1/1, then ethyl acetate). The resulting residue is suspended in n-hexane, and collected by filtration to give the title compound (60 mg).
