Procedure

Methyl 2-{[(5-chloropyridin-2-yl)amino]carbonyl}-3-[({trans-4-[(dimethylamino)carbonyl]cyclohexyl}carbonyl)-amino]benzofuran-5-carboxylate (1.35 g) obtained in Example 1 is suspended in tetrahydrofuran-methanol (4:1) (20 ml). After adding a solution of sodium hydroxide (205 mg) in water (5 ml), the mixture is warmed to room temperature and stirred for 18 hours. The reaction solution is concentrated under reduced pressure, thereto poured ice-water, and the mixture is acidified by addition of 10% hydrochloric acid. The precipitates are collected by filtration, washed with water, and dried to give the title compound (1.23 g).
