실험 절차

A solution of 5-(2,6-difluorophenyl)-3-iodo-1-(tetrahydro-2H-pyran-2-yl)-1H-indazole (400 mg, 0.91 mmol) and tert-butyl 1-(6-(tributylstannyl)pyrazin-2-yl)piperidin-3-ylcarbamate (520 mg, 0.91 mmol) in DMF (9.1 mL) was purged with N2 for 15 min and added CuI (225 mg, 1.18 mmol) and Pd(PPh3)4 (105 mg, 0.09 mmol). The reaction mixture was heated at 80° C. for 2 h and cooled to RT. To the reaction mixture was added water and precipitate was formed. The precipitate was collected by filtration, washed with water and dried overnight to give crude product. The crude was purified by chromatography (eluting with 0-10% MeOH and DCM) to obtain the title compound (350 mg, 66% yield). MS (ESI, pos. ion) m/z: 591 (M+1).
