Procedure

A suspension of 2-benzenesulfonylamino-5-methylthio-3-iodo-pyridine (1.53 g), 2-ethynylpyrimidine (768 mg), bistriphenylphosphine palladium dichloride (259 mg) and cuprous iodide (70.3 mg) in triethylamine (37 ml) was stirred in a sealed tube at 100° C. for 1.5 hours. After cooling, the reaction solution was poured into water, extracted with chloroform, dried over, anhydrous sodium sulfate, filtered and concentrated under reduced pressure. The resulting residue was separated using silica gel column chromatography (hexane:ethyl acetate=1:1) to obtain 1.21 g of the desired product as a white crystal.
