Procedure

A microwave vessel was charged with 2-[4-(4-morpholin-4-yl-2-tributylstannanyl-thieno[3,2-d]pyrimidin-6-ylmethyl)-piperazin-1-yl]-isobutyramide (0.200 g, 0.288 mmol), 5-bromoisoquinoline (0.072 g, 0.346 mmol), copper(I)iodine (0.066 g, 0.346 mmol), palladium tetrakis(triphenylphosphine) (0.033 g, 0.029 mmol) and dioxane (4 mL) The vessel was evacuated and back-filled with argon three times then sealed and heated at 140° C. under microwave irradiation for 20 min. The reaction mixture was cooled to room temperature and filtered through celite. The filtrates were concentrated then purified by chromatography (silica, 0 to 15% of a 9:1 MeOH:NH4OH mixture in dichloromethane) to give a yellow residue. This residue was dissolved in dichloromethane then 1 N HCl in ether (0.2 mL) added dropwise. The resulting precipitate was collected by filtration to furnish 135 (0.012 g, 6%) as a pale yellow powder and as a tetrahydrochloride salt.
