Procedure

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 (0.150 g, 0.380 mmol), 7-chloroquinoline-4-boronic acid pinacol ester (0.132 g, 0.456 mmol), dichlorobis(triphenylphosphine)palladium(II) (0.013 g, 0.02 mmol), 1 N aqueous sodium carbonate solution (1 mL) and acetonitrile (3 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 ethyl acetate and filtered through celite. The filtrates were concentrated then purified by chromatography (silica, 10 to 20% methanol in dichloromethane) to give 104 (0.085 g, 43%) as a yellow solid.
