[(5R)-3-(5-Bromopyridin-2-yl)-4,5-dihydroisoxazol-5-yl]methanol (Intermediate 12, 0.5 g, 1.95 mmol), (0.35 g, 0.9 mmol), potassium carbonate (0.622 g, 4.5 mmol), N-({(5S)-3-[3-fluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]-2-oxo-1,3-oxazolidin-5-yl}methyl)acetamide (Intermediate 13, 0.736 g, 1.95 mmol) and tetrakis(triphenylphosphino)palladium(0) (0.225 g, 0.195 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, dried under vaccum and collected as the title compound (0.42 g)
