Procedure

To a solution of 4-chloro-6-(4-methylpiperazin-1-yl)pyrimidin-2-amine (20 mg, 0.09 mmol, Example 1) and 1,4-dihydroisoquinolin-3(2H)-one (16 mg, 0.10 mmol, Tyger, Cat. No. D30080) in 1,4-dioxane (1 mL) was added (9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine) (20 mg, 0.04 mmol, Aldrich, Cat. No. 526460), palladium acetate (4 mg, 0.02 mmol, Aldrich, Cat. No. 205869) and cesium carbonate (60 mg, 0.2 mmol, Aldrich, Cat. No. 202126). The mixture was degassed with nitrogen and heated at 100° C. 20 h. The reaction mixture was concentrated under reduced pressure. The residue was dissolved in MeOH, and purified by RP-HPLC (pH=10 system) to afford the desired compound.
