Procedure

1.500 g of 1-(6-bromo-quinolin-4-yl)-3-(6-trifluoromethyl-pyridin-2-yl)-urea (3.65 mmol), 1.692 g of tert-butyl 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-5,6-dihydropyridine-1(2H)-carboxylate (5.47 mmol), 0.422 g of tetrakis(triphenylphosphine)palladium(0) (0.365 mmol) and 8.21 ml of a 2M sodium carbonate solution (16.42 mmol) were dissolved/suspended in 32 ml DMF in a microwave vessel, flushed with vacuum/argon, and subsequently heated in the microwave for 1 h at 80° C. HPLC/MSD indicated almost complete formation of the desired product. The reaction mixture was poured on ice, stirred for 1 h, and the precipitation formed was filtered off and dried in vacuum for 24 h. 2 g of the desired product were obtained as an off white powder (yield: quant.). The quite pure raw material was used without further purification in the next step.
