Reaction Steps

A mixture of 0.12 g (0.48 mmol) trifluoro-methanesulfonic acid 2-methyl-pyridin-3-yl ester, 0.13 g (0.52 mmol) bis(pinacolato)diboron, 0.14 g (1.4 mmol) potassium acetate and 0.02 g (0.02 mmol) dichloro[1,1′-bis(diphenylphosphino) ferrocene]palladium(II) dichloromethane adduct in 2.5 ml N,N-dimethylformamide was heated at 80° C. over night under argon. After cooling to room temperature 0.10 g (0.16 mmol) (2S,4R)-2-(3,5-bis-trifluoromethyl-phenyl)-N-[6-(4-hydroxy-2-hydroxymethyl-pyrrolidin-1-yl)-4-iodo-pyridin-3-yl]-N-methyl-isobutyramide and 1.3 ml of a deoxygenated 2 M aqueous solution of sodium carbonate were added. The reaction mixture was heated at 80° C. for 6 h. After cooling to room temperature the mixture was diluted with water and extracted with three portions of tert-butyl methyl ether. The combined organic layers were dried over sodium sulfate and concentrated in vacuo. Flash column chromatography gave 37 mg (39%) of the title compound as an off-white solid.
