Reaction Steps

A mixture of 4-(7-bromo-3,4-dihydroisoquinolin-2(1H)-yl)-6-(4-methylpiperazin-1-yl)pyrimidin-2-amine (40 mg, 0.1 mmol), piperidine-4-carbonitrile (22 mg, 0.20 mmol, Oakwood, Cat. No. 024547), sodium tert-butoxide (23 mg, 0.24 mmol), 2-(2′-di-tert-butylphosphine)biphenyl palladium(II) acetate (2.8 mg, 0.0060 mmol, Aldrich, Cat. No. 655414) in 1,4-dioxane (1 mL) was degassed with nitrogen and then heated at 120° C. overnight. 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=433.3.
