Reaction Steps
Under a nitrogen atmosphere, trifluoroacetic acid (1 mL) was added dropwise to a stirred ice-cold solution of (2S)-N-(tert-butoxycarbonyl)-2-(2-(3-pyridyl)vinyl)pyrrolidine (280 mg, 1.02 mmol) in anisole (2 mL). The reaction mixture was allowed to warm to room temperature, stirred for 16 h, then neutralized with saturated aqueous NaHCO3 solution, saturated with solid NaCl and extracted with chloroform (5×10 mL). The combined chloroform extracts were dried (K2CO3), filtered and concentrated on a rotary evaporator to give a viscous dark oil, which was chromatographed with chloroform:methanol (9:1, v/v) and 1% triethylamine as eluant. Selected fractions containing the product were combined and concentrated on a rotary evaporator to give 130 mg (73.1% yield) of a colorless oil.
