A solution of tert-butyl N-[(3S)-1-[6-(6-chloropyrazolo[4,3-c]pyridin-1-yl)-2-pyridyl]-2-oxo-3-piperidyl]carbamate (125 mg, 0.282 mmol) and palladium(0)tetrakis(triphenylphosphine) (32 mg, 0.028 mmol) in N,N-dimethylacetamide 5.0 mL was added trimethyl-(6-methylpyrazin-2-yl)stannane (145 mg, 0.565 mmol). The reaction mixture heated at 145° C. for 40 min in CEM microwave. The reaction mixture was filtered through celite and concentrated. The crude product was diluted with EtOAc then washed with water. The organic layers was dried with sodium sulfate, filtered, and concentrated in vacuum. The crude product was carried to next step. MS (ESI) m/z: 501.1.
