実験手順

[(5S)-3-(5-Bromopyridin-2-yl)-4,5-dihydroisoxazol-5-yl]methanol (Intermediate 11, 0.277 g, 1.08 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, 0.35 g, 0.9 mmol), potassium carbonate (0.622 g, 4.5 mmol), and tetrakis(triphenylphosphino)palladium(0) (0.1 g, 0.09 mmol) were combined and suspended in DMF (7 ml) and water (1 ml). The mixture was heated at 75° C. for 2 hours, then was poured into cold water (30 ml). The solids formed were collected, rinsed with water and washed with dichloromethane (2×10 ml), the solids were then dissolved in warm trifluoroethanol (2 ml), and further purified by column chromatography, eluting with 8% methanol in dichloromethane to give the title compound as a white solid (0.193 g).
