A mixture of 4-chloro-6-(4-methylpiperazin-1-yl)pyrimidin-2-amine (0.10 g, 0.44 mmol), tert-butyl 7-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-3,4-dihydroisoquinoline-2(1H)-carboxylate (0.16 g, 0.44 mmol), [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II)dichloromethane (1:1) complex (0.02 g, 0.02 mmol) and potassium carbonate (0.18 g, 1.3 mmol) in 1,4-dioxane (3 mL), and water (1 mL) was heated at 110° C. overnight. After cooled to r.t., the mixture was diluted with MeOH, filtered, and concentrated under reduced pressure. The residue was purified by flash chromatography on a silica gel column eluting with 10% MeOH in dichloromethane (DCM) to afford the desired product (0.14 g, yield: 75%). Analytic LCMS (M+H)+: m/z=425.4.
