Procedure

A mixture of 2-[4-(4-morpholin-4-yl-2-(tributylstannanyl)thieno[3,2-d]pyrimidin-6-ylmethyl)piperazin-1-yl]isobutyramide (150 mg, 0.22 mmol), 1-benzenesulfonyl-4-bromo-1H-pyrrolo[3,2-c]pyridine (90 mg, 0.27 mmol), Pd(PPh3)4 (25 mg, 10 mol %) and CuI (50 mg, 0.25 mmol) in dioxane (2.5 mL) was purged with argon gas then heated at 140° C., for 20 min, in a microwave reactor. The reaction mixture was loaded onto an Isolute® SCX-2 cartridge, washed with MeOH/DCM then eluted with 2 M NH3 in MeOH. The resulting residue was dissolved in IMS/dioxane (1:1 mL) and 12.5 M aqueous NaOH solution (0.1 mL) added. After stirring for 1 h the reaction mixture was loaded onto an Isolute® SCX-2 cartridge, washed with MeOH/DCM then eluted with 2 M NH3 in MeOH/DCM. The resulting residue was purified by flash chromatography (Si—PPC, MeOH:DCM, gradient 0:100 to 05:95) to give 106 (28 mg, 24%) as a pale yellow solid.
