実験手順

The compound (625 mg, 0.901 mmol) obtained in Example 1j was dissolved in dichloromethane (9 mL), triethylamine (0.376 mL, 2.70 mmol) and isobutyl chloroformate (183 μL, 1.35 mmol) were added under ice cooling, and the mixture was stirred at the same temperature. The compound (467 mg, 2.70 mmol) obtained in Example 68a was added under ice cooling, and then the temperature was increased to room temperature. After the reaction was completed, a saturated aqueous sodium hydrogencarbonate solution was added, and the mixture was extracted with dichloromethane (×2). The resulting organic layer was dried with anhydrous sodium sulfate, and the solvent was evaporated under reduced pressure. The resulting residue was purified by NH silica gel column chromatography (a elution solvent, ethyl acetate) to give the title compound (615 mg; yield, 79%).
