実験手順

A solution of sodium bicarbonate (10.0 mg, 0.12 mmol) in water (267 μL) was added dropwise via syringe to a stirred solution of 4d (0.108 mmol) in dioxane (1.0 mL) at room temperature. A suspension of cyanogen bromide (13.0 mg, 0.12 mmol) in dioxane (120 μL) was added in 4 equal portions at 1 minute intervals. After approximately 45 min, 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% TiFA as modifier). Lyophilization of the purified fractions afforded the title compound 5b, m/z (ES) 489 (MH)+.
