Procedure

2-{[(5-Chloropyridin-2-yl)amino]carbonyl}-3-[({trans-4-[(dimethylamino)carbonyl]cyclohexyl}carbonyl)amino]-benzofuran-5-carboxylic acid (200 mg) obtained in Example 5 is suspended in chloroform-pyridine (1:3) (8 ml), and thereto are added successively dimethylamine hydrochloride (64 mg), 1-hydroxybenzotriazol (79 mg) and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (112 mg) under ice-cooling. The mixture is then stirred at room temperature for 17 hours. To the reaction solution is poured a saturated aqueous sodium hydrogen carbonate solution, and the mixture is extracted with chloroform. The organic layer is washed with saturated brine and dried over sodium sulfate. After evaporating the solvent under reduced pressure, the resulting residue is suspended in ethanol-diethyl ether. The precipitates are collected by filtration and dried to give the title compound (176 mg).
