Reaction Steps
A mixture of 4-chloro-6-(4-methylpiperazin-1-yl)pyrimidin-2-amine (0.075 g, 0.33 mmol), 5-[7-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-3,4-dihydroisoquinolin-2(1H)-yl]pyridine-2-carbonitrile (0.12 g, 0.33 mmol), [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II)dichloromethane (1:1) complex (0.01 g, 0.02 mmol) and potassium carbonate (0.14 g, 0.99 mmol) in 1,4-dioxane (2 mL), and water (1 mL) was heated at 120° C. for 2 h. After cooled to r.t., the mixture was diluted with MeOH, filtered, concentrated under reduced pressure. The residue was purified by flash chromatography on a silica gel column eluting with 10% MeOH in DCM to give the desired product. The product was further purified by RP-LCMS (pH=10) to afford the desired product (0.10 g, yield: 71%). Analytic LCMS (M+H)+: m/z=427.3.
