실험 절차

A solution of (2S,4S)-1-(tert-butoxycarbonyl)-4-fluoropyrrolidine-2-carboxylic acid (500 mg, 2.14 mmol) in THF (15 mL) was treated with a 1N solution of BH3-THF complex (4.29 mL, 4.29 mmol). The mixture was stirred at ambient temperature for 12 hours then quenched with MeOH and concentrated under reduced pressure. The residue was purified by column chromatography using an Analogix® Intelliflash280™ (SiO2, 0-100% ethyl acetate in hexanes) to afford the title compound (425 mg, 90%). MS (DCI/NH3) m/z 220 (M+H)+.
