실험 절차

DIPEA (114 μl) was added to a solution of the compound obtained in Step 2 of Example 8 (91 mg) and COMU (181 mg) in DMF (2.0 ml) at room temperature, and the mixture was stirred for 20 minutes. The compound obtained in Step 1 of Example 1 (95 mg) was added at room temperature. The mixture was stirred for six hours, followed by the addition of water. After extraction with ethyl acetate, the organic layer was washed with brine and then dried over sodium sulfate. The solvent was distilled off under reduced pressure, and the residue was purified by silica gel column chromatography [chloroform:methanol=300:1->30:1 (v/v)] to give 139 mg of the title compound as a solid.
