Participants

Reaction Steps

The compound (100 mg, 0.224 mmol) obtained in step 1, M-5 (49.9 mg, 0.291 mmol), and WSC hydrochloride (64.4 mg, 0.336 mmol) were dissolved in pyridine (0.5 mL), and the mixture was stirred at room temperature overnight. The reaction mixture was concentrated under reduced pressure, trifluoroacetic acid (1.0 ml) was added to the obtained residue, and the mixture was stirred at room temperature for 30 minutes. The reaction mixture was concentrated under reduced pressure and the obtained residue was purified by high performance liquid chromatography (water-acetonitrile, each containing 0.1% trifluoroacetic acid) to give the title compound (98.5 mg, 0.181 mmol, 81%).
