t-Butyl [2-{[(5-Chloropyridin-2-yl)amino]carbonyl}-3-({[trans-4-(3-oxomorpholin-4-yl)cyclohexyl]carbonyl}amino)furo[3,2-b]pyridin-5-yl]carbamate (5.55 g) obtained in Example 94 is suspended in methanol (20 ml), and thereto is added 4N hydrogen chloride-dioxane solution (50 ml) under ice-cooling. The mixture is stirred at room temperature for 8 hours. The reaction solution is concentrated under reduced pressure and the resulting residue is suspended in diethyl ether. The precipitates are collected by filtration to give the title compound (4.67 g).
