Reaction Steps

A microwave vial was charged with 3-bromo-5-[(S)-2-(tert-butyl-dimethyl-silanyloxymethyl)-pyrrolidin-1-yl]-pyridine (0.091 g, 0.245 mmol), 1-methyl-6-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-3,4-dihydro-1H-quinolin-2-one (intermediate A-1, 0.077 g, 0.270 mmol) and DMF (1.5 mL). The reaction mixture was purged with Argon; then, bis(triphenylphosphine)palladium(II)chloride (0.017 g, 0.025 mmol), followed by a 1N Na2CO3 aqueous solution (0.980 mL, 0.980 mmol) were added and the reaction mixture was heated in the microwave at 120° C. for 30 min. The reaction mixture was diluted with EtOAc, poured into aq. NaHCO3 (10 mL) and the aqueous layer was extracted with EtOAc (2×40 mL). Combined organics were washed with brine, dried over Na2SO4, filtered and evaporated. The residue was purified by silica gel flash chromatography eluting with a 0 to 5% MeOH-DCM gradient to give the title compound (0.1 g, 90%) as a white solid. MS: 452.1 (M+H+).
