Reaction Steps

To a solution of the compound obtained in Example 29 (2) (0.1 g) in N,N-dimethylformamide (1 ml), 2-benzenesulfonylamino-3-iodo-5-methanesulfonylbenzene (0.0925 g), bistriphenylphosphine palladium dichloride (0.015 g), cuprous iodide (0.004 g) and potassium acetate (0.04 g) were added successively and the mixture was stirred in a sealed tube at 100° C. for 2 hours. After cooling, the reaction solution was poured into water, extracted with ethyl acetate, washed with a saturated aqueous NaCl solution, dried over anhydrous magnesium sulfate, filtered and concentrated under reduced pressure. The resulting residue was separated using silica gel column chromatography (hexane:ethyl acetate=1:1) to obtain 0.0462 g of the desired product as a brown solid.
