Reaction Steps

4-Methylthio-6-iodo-thieno[2,3-d]pyrimidine (Intermediate 91) (949 mg), 5-tributylstannyl-4-iodo-1-methyl-1H-imidazole (Intermediate 92) (2.76 g) and tetrakis(triphenylphosphine)palladium(0) (178 mg) were stirred in anhydrous DMF (50 mL), degassed with nitrogen for 10 min, then heated to 100° C. for 18 hours under an inert atmosphere. The reaction mixture was concentrated in vacuo and the crude product triturated with DCM (20 mL) to afford the title compound as a yellow solid (805 mg, 67%);
