実験手順

A mixture of 6-(2,6-difluoro-3,5-dimethoxyphenyl)-3-iodo-1H-pyrazolo[3,4-d]pyrimidine (16.7 mg, 0.0400 mmol), tert-butyl 7-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-3,4-dihydroisoquinoline-2(1H)-carboxylate (17.96 mg, 0.05000 mmol), [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II) complex with dichloromethane (1:1) (2.0 mg, 0.0024 mmol) and potassium phosphate (25.5 mg, 0.120 mmol) in 1,4-dioxane (0.50 mL) and water (0.15 mL) in a reaction vial was sealed, and degassed and recharged with nitrogen for three times. The mixture was stirred at 115° C. for 3 h. After cooling, the mixture was diluted with methanol, and purified by RP-HPLC (pH=10) to afford the desired product. LCMS (M+H)+=524.1.
