실험 절차

A solution of 205 (15 mmol) in dimethylformamide (30 mL) is cooled to 0° C. and treated with imidazole (30 mmol) and triethylsilyl chloride (20 mmol). The resultant solution is warmed to room temperature. After 12 h, the reaction mixture is poured into 300 mL of water and extracted with ether (3×40 mL). The ethereal extracts are washed with water (2×25 mL) and saturated aqueous brine (25 mL), dried over magnesium sulfate and concentrated in vacuo. The residue is purified by flash chromatography to afford 206.
