[(5S)-3-(5-Bromopyridin-2-yl)-4,5-dihydroisoxazol-5-yl]methyl β-D-glucopyranoside (Intermediate 20, 0.150 g, 0.36 mmol), (5R)-3-[3-fluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]-5-(1H-1,2,3-triazol-1-ylmethyl)-1,3-oxazolidin-2-one (Intermediate 7, 0.153 g, 0.39 mmol), sodium carbonate (0.152 g, 1.43 mmol), and tetrakis(triphenylphosphino)palladium(0) (0.041 g, 0.036 mmol) were mixed in DMF/water (10:1, 5 mL) under nitrogen and heated at 70° C. bath temperature for 4 hours. The solvent was evaporated under reduced pressure. Chromatography on silica gel with dichloromethane/methanol 5:1 followed by crystallization from ethanol gave the product as colourless solid (83 mg). MS (ESP): 601.06 (MH+) for C27H29FN6O9
