実験手順

To a solution of compound 7 (207 mg, 0.50 mmol) in DMF (5 mL) were added N,N-diisopropylethylamine (174 uL, 1.0 mmol) and acetoxyacetyl chloride (65 uL, 0.60 mmol) and the resulted mixture was stirred at room temperature for 1 hr. The reaction mixture was concentrated to give compound 189 as a yellow solid which was used in next step without further purification. LCMS-ESI (POS), M/Z, M+1: Found 514.2, Calculated 514.2.
