A mixture of 1,1-dimethylethyl 4-(6-bromo-1,2-benzisoxazol-3-yl)-1-piperazinecarboxylate (Intermediate 25) (0.04 g), N-Cyclopropyl-4-methyl-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzamide (Intermediate 5) (0.035 g), 2N aqueous sodium carbonate (2 ml) and tetrakis(triphenylphosphine)palladium(0) (1 mg) in isopropanol (6 ml) was stirred at reflux under nitrogen for 16 h. The residue was absorbed onto silica Merck 7734) and applied to a Varian Bond-Elut SPE cartridge (silica, 5 g). Elution with dichloromethane:methanol (98:2) gave the title compound as a cream solid (0.03 g).
