実験手順

A catalytic amount of p-TSA (˜3 mg) was added to a stirred suspension of 4d HCl salt (54.6 mg, 0.10 mmol) in triethylorthoformate (600 μL) at room temperature. After 30 min, 1N hydrochloric acid (600 μL) was added, and the resulting solution was aged for an additional 45 min. The reaction mixture was poured into saturated aqueous sodium bicarbonate and extracted three times with EtOAc. 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 Sc, m/z (ES) 474 (MH)+.
