実験手順

A mixture of Intermediate 5 (150 mg, 0.45 mmol) and triethylamine (0.063 mL, 0.54 mmol) was stirred in dichloromethane (6 mL) at room temperature. Acetic acid anhydride (0.051 mL, 0.54 mmol) was added and the reaction mixture was stirred at room temperature for 2 h. The reaction mixture was washed with a potassium carbonate solution. The organic layer was dried on MgSO4, filtered, and evaporated. The residue was purified by preparative HPLC (RP Shandon Hyperprep C18 BDS—8 μm, 250 g, 5 cm; mobile phase (0.25% NH4HCO3 solution in water, MeOH+CH3CN)), yielding 100 mg (59%) of Compound 60.
