Procedure

A mixture of 8-fluoro-1-methyl-6-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-3,4-dihydro-1H-quinolin-2-one (20 mg, 0.066 mmol), ethanesulfonic acid (5-bromo-pyridin-3-ylmethyl)-amide (intermediate A-11, 27.4 mg, 0.098 mmol), bis(triphenylphosphine)-palladium(II) chloride (4.6 mg, 0.0066 mmol) and aq. sodium carbonate solution (2 N, 0.07 mL) in DMF (1 mL) was heated in a microwave at 120° C. for 30 min. The resulting reaction mixture was then diluted with EtOAc, washed with water, dried over sodium sulfate and concentrated in vacuo. The residue was purified by prep-HPLC to afford the title compound (12.4 mg, 50%) as a white solid. MS: 378.1 (M+H+)+.
