実験手順

The compound (400 mg, 0.576 mmol) obtained in Example 1j was dissolved in dichloromethane (30 mL), triethylamine (0.12 mL, 1.04 mmol) and pivaloyl chloride (0.11 mL, 0.864 mmol) were added under ice cooling, and the mixture was stirred at the same temperature under a nitrogen atmosphere for 15 minutes. Subsequently, a solution of 4-(methylamino)butan-1-ol (178 mg, 1.73 mmol) in dichloromethane (2 mL) was added under ice cooling, and the mixture was stirred at room temperature under a nitrogen atmosphere for 16 hours. After the reaction was completed, a saturated aqueous sodium hydrogencarbonate solution was added, and ethyl acetate was further added to separate the layers. The resulting organic layer was separated, washed with saturated sodium chloride solution, and then dried with anhydrous sodium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by NH silica gel column chromatography (hexane:ethyl acetate, 10:1, v/v) to give the title compound (347 mg; yield, 77%) as a colorless oily substance.
