実験手順

Bring a mixture of trifluoro-methanesulfonic acid 3,5-dichloro-4-[(R)-2-oxo-1-(4-triisopropylsilanyloxy-piperidin-1-yl)-pyrrolidin-3-ylmethyl]-phenyl ester (0.18 g, 0.29 mmol), 4-trifluoromethylphenylboronic acid (0.07 g, 0.36 mmol), sodium carbonate (0.09 g, 0.86 mmol) in THF (26 mL) and water (13 mL) to 60° C. To the mixture at 60° C., add Pd(PPh3)4 (0.02 g, 0.01 mmol). Raise the reaction temperature to 80° C. and stir for 1 hour. Cool the reaction, dilute with ethyl acetate, and wash with water and brine. Dry the organic layer (Na2SO4), remove the solvent in vacuo to afford crude product, and purify on silica gel column with 25% to 50% ethyl acetate in hexanes gradient to afford 0.12 g of (R)-3-(3,5-Dichloro-4′-trifluoromethyl-biphenyl-4-ylmethyl)-1-(4-triisopropylsilanyloxy-piperidin-1-yl)-pyrrolidin-2-one.
