Procedure

A sealable tube was charged with 2-chloro-4-morpholin-4-yl-6-(4-morpholin-4-yl-piperidin-1-ylmethyl)-thieno[3,2-d]pyrimidine (0.100 g, 0.229 mmol), isoquinoline-5-boronic acid (0.048 g, 0.275 mmol), dichlorobis(triphenylphosphine)palladium(II) (0.008 g, 0.012 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 101 (0.033 g, 27%) as a yellow solid.
