Reaction Steps

To a solution of (S)-2-bromo-N-(1-(8-chloro-1-oxo-2-phenyl-1,2-dihydroisoquinolin-3-yl)ethyl) nicotinamide (52) (125 mg, 0.26 mmol) in a 1:1 mixture of DMF and EtOH (9 mL), 1H-pyrazole-4-boronic acid (37 mg, 0.34 mmol), tetrakis(triphenylphosphine)palladium (0) (21 mg, 0.018 mmol) and aqueous Na2CO3 solution (1.0 M, 0.78 mL, 0.78 mmol) were added sequentially. The resulting mixture was stirred at 85° C. for 16 h. The mixture was allowed to cool to RT and then partitioned between ethyl acetate and water. The organic layer was washed with brine, dried over Na2SO4 and filtered. The filtrate was concentrated in vacuo and the residue was purified by prep-TLC plate (10% MeOH-DCM) to afford the product (S)—N-(1-(8-chloro-1-oxo-2-phenyl-1,2-dihydroisoquinolin-3-yl)ethyl)-2-(1H-pyrazol-4-yl)nicotinamide (compound 58). ESI-MS m/z: 471.0 [M+H]+.
