A mixture of N-cyclopropyl-4-methyl-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzamide (Intermediate 5) (0.04 g) 2-(6-bromo-1,2-benzisoxazol-3-yl)-N-(2-hydroxyethyl)acetamide (Intermediate 35) (0.04 g) 2M aqueous sodium carbonate (1.5 ml) and tetrakis(triphenylphosphine)palladium(0) (1 mg) in isopropanol (3 ml) was stirred at reflux under nitrogen for 18 h. The mixture was absorbed onto silica (Merck 7734) and applied to a Varian Bond-Elut SPE cartridge (silica, 5 g) and eluted with a toluene:ethanol gradient (100:0 to 0:100) to give the title compound as a white solid (0.03 g).
