Reaction Steps

To a suspension of PPh3 (PPh3 polymer bound, 3 mmol PPh3/g resin) (141 mg, 0.53 mmol) in THF (8 mL) at 0° C. were added 5-chloro-pyridin-2-ol (47 mg, 0.36 mmol) and then DBAD (90 mg, 0.39 mmol). After 5 minutes was added (R)-1-[(3R,4S)-1-benzyl-4-(3-chloro-4-fluoro-phenyl)-pyrrolidin-3-yl]-ethanol (81 mg, 0.24 mmol). The reaction mixture was stirred over night at RT, filtered on celite and concentrated under vacuo. Extraction with EtOAc/aq.NaOH 1M, followed by column chromatography (SiO2, EtOAc/H, 1:3) yielded 88 mg (81%) of the title compound as a colorless oil. ES-MS m/e: 446.2 (M+H+).
