반응 단계

A mixture of commercially available 2-(4-Bromo-phenyl)-pyrrolidine-1-carboxylic acid tert-butyl ester (500 mg, 1.53 mmol), 2,2-dichloro-N-((1R,2S)-3-fluoro-1-hydroxy-1-(4-(trimethylstannyl)phenyl)propan-2-yl)acetamide (679 mg, 1.53 mmol, 1 eq.), P(2-fur)3 (72 mg, 0.31 mmol, 0.2 eq.) and Pd2(dba)3 (142 mg, 0.153 mmol, 0.1 eq.) are dissolved in DMF (8 mL, 0.2 M) and de-oxygenated. The mixture is heated to 80° C. for 16 hours. Reaction is concentrated under vacuum to a syrup and purified on a 24 g silica column eluting from 0-100% EtOAc/heptane) to give the title compound 240 mg.
