HCID 21877175AcOH THF water溶媒

実験手順

The dioxolane (step 3) (500 mg, 1.42 mmoles) was heated at reflux in 9 mL of THF:AcOH:H2O 6:2:1 for 2 hours. Addition of 25% NH4OAc, extraction with EtOAc, drying, evaporation, and flash chromatography on silica with EtOAc:toluene 2.5:97.5 afforded the title compound.
