DIPEA (414 μl) was added to a solution of the compound obtained in Step 2 of Example 9 (500 mg) and COMU (883 mg) in DMF (8.0 ml) at room temperature, and the mixture was stirred for 25 minutes. The compound obtained in Step 1 of Example 1 (440 mg) was added at room temperature. The mixture was stirred for 19 hours, followed by the addition of water. The precipitated solid was collected by filtration, suspended in chloroform/diisopropyl ether and then collected by filtration to give 800 mg of the title compound.
