A sealable tube was charged with [1-(2-chloro-4-morpholin-4-yl-thieno[3,2-d]pyrimidin-6-ylmethyl)-piperidin-4-yl]-dimethyl-amine (0.630 g, 1.59 mmol), isoquinoline-5-boronic acid (0.331 g, 1.91 mmol), dichlorobis(triphenylphosphine)palladium(II) (0.056 g, 0.08 mmol), 1 N aqueous sodium carbonate solution (2.5 mL) and acetonitrile (7.5 mL). The vessel was evacuated and back-filled with argon three times then sealed and heated at 130° C. for 90 min. The reaction mixture was cooled, concentrated, redissolved in methanol and filtered through celite. The filtrates were concentrated then purified by chromatography (C-18 reverse phase column, 5 to 95% acetonitrile in water containing 0.1% TFA). The fractions containing the desired product were concentrated then dissolved in MeOH/dichloromethane, basified with solid sodium carbonate then filtered and concentrated to furnish 109 (0.386 g, 50%) as a white foam.
