HCID 8028Tetrahydrofuran溶媒

実験手順

The compound (375 mg, 0.70 mmol) obtained in Example 61-1) was dissolved in tetrahydrofuran (7 mL). Tetrabutylammonium fluoride (1.0 mol/L tetrahydrofuran solution, 0.84 mL, 0.84 mmol) was added to the solution at room temperature, and the mixture was stirred at room temperature for 1 h under a nitrogen atmosphere. Saturated aqueous sodium hydrogencarbonate (10 mL) was added to the reaction mixture, and the mixture was extracted with ethyl acetate (50 mL). The organic layer was washed with saturated sodium chloride solution and then dried with anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure, and the obtained residue was purified by silica gel column chromatography (elution solvent: methanol/ethyl acetate=10% to 40%) to obtain the title compound (208 mg, 71%) in a white solid form.
