A mixture of 4-(7-bromo-3,4-dihydroisoquinolin-2(1H)-yl)-6-(4-methylpiperazin-1-yl)pyrimidin-2-amine (22.4 mg, 0.0556 mmol), (9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine) (12.9 mg, 0.0222 mmol, Aldrich, Cat. No. 526460), palladium acetate (2.50 mg, 0.0111 mmol, Aldrich, Cat. No. 379875), cesium carbonate (36.2 mg, 0.111 mmol) and urethane (7.43 mg, 0.0834 mmol, Aldrich, Cat. No. 418331) in 1,4-dioxane (1 mL) was degassed with nitrogen and then heated at 120° C. for 20 h. The reaction mixture was cooled to r.t. and concentrated under reduced pressure. The residue was dissolved in MeOH and purified by RP-HPLC (pH=10) to afford the desired compound. LCMS (M+H)+: m/z=412.2.
