Reaction Steps

A suspension of the compound obtained in Example 5 (1) (100 mg), 2-ethynylpyridine (30.4 mg), bis(triphenylphosphine) palladium(II) dichloride (17.3 mg) and cuprous iodide (4.7 mg) in triethylamine (2.5 ml) was stirred in a sealed tube at 100° C. for 1 hour. After completion of the reaction, the reaction suspension was poured into water, extracted with methylene chloride, washed with a saturated aqueous NaCl solution, dried over anhydrous sodium sulfate, filtered and concentrated under reduced pressure. The resulting residue was separated using silica gel preparative thin-layer chromatography (hexane:ethyl acetate=1:1) to obtain 71.9 mg of the desired product as a colorless oil.
