実験手順

Phosgene (751 μL of a −20% w/v solution in toluene, 1.42 mmol) was added dropwise via syringe to a stirred solution of 4d (365 mg, 0.79 mmol) in methylene chloride (20 mL) at −78° C. After approximately 45 minutes, the reaction mixture was poured into saturated aqueous sodium bicarbonate and extracted three times with methylene chloride. The combined organic extracts were washed with brine, dried (Na2SO4) and concentrated in vacuo. The crude residue was purified by preparative reversed phase HPLC on YMC Pack Pro C18 stationary phase (gradient elution; 0-75% acetonitrile/water as eluent, 0.1% TFA as modifier). Lyophilization of the purified fractions afforded the title compound 4e, m/z (ES) 490 (MH)+.
