Procedure

To a mixture of (S)-3-(1-aminoethyl)-8-chloro-2-phenylisoquinolin-1(2H)-one (1) (1.0 g, 3.35 mmol) and 1-methyl-1h-pyrazole-4-boronic acid (815 mg, 5.02 mmol) in anhydrous DMA (10 mL) in a sealed tube, PdCl2(dppf) (219 mg, 0.27 mmol) and aqueous Na2CO3 solution (1 M, 10.0 mL, 10.0 mmol) were added and the resulting mixture was stirred at 120° C. for 3 h. The reaction mixture was allowed to cool to RT, quenched with water, and then extracted with ethyl acetate (200 mL×3). The combined organic layers were washed with brine, dried over Na2SO4 and filtered. The filtrate was concentrated in vacuo and the residue was purified by ISCO (silica gel cartridge, 0-8% MeOH-DCM) to afford the product, (S)-3-(1-aminoethyl)-8-(1-methyl-1H-pyrazol-4-yl)-2-phenylisoquinolin-1(2H)-one (63) (990 mg, 85% yield) as a pink/magenta solid. ESI-MS m/z: 345.2 [M+H]+.
