Procedure
To a mixture of 7-fluoro-1-methyl-6-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-3,4-dihydro-1H-quinolin-2-one (intermediate A-22, 168 g, 0.55 mmol) and N-(5-bromo-pyridin-3-ylmethyl)-propionamide (122 mg, 0.5 mmol) in DMF (3 mL), purged with argon for 1 min, was added bis(triphenylphosphine)palladium (II)chloride (38 mg, 0.054 mmol) and 1 N aq. Na2CO3 (2.5 mL). Then, the resulting reaction mixture was heated in a microwave at 110° C. for 45 min. After cooling to room temperature, it was diluted with EtOAc (5 mL) and poured into a satd. aq. solution of NaHCO3 (10 mL). The aqueous layer was extracted with EtOAc (3×5 mL) and combined organics were washed with water and brine (20 mL), dried over anhydrous Na2SO4, filtered and concentrated in vacuo. The residue was then purified by prep-HPLC to afford the title compound (30 mg, 18%) as a white solid. MS: 342.1 (M+H+)+.
