Reaction Steps
DIPEA (120 μl) was added to a solution of the compound obtained in Step of Example 3 (80 mg) and COMU (192 mg) in DMF (1.5 ml) at room temperature, and the mixture was stirred for 10 minutes. The compound obtained in Step 1 of Example 1 (100 mg) was added at room temperature. The mixture was stirred for four hours, followed by the addition of water. The precipitated solid was collected by filtration to give 174 mg of the title compound.
