Reaction Steps

To a solution of the compound obtained in Example 34 (2) (440 mg) in dioxane (10 ml), 2-propyn-1-ol (168 mg), bistriphenylphosphine palladium dichloride (72 mg), copper(I) iodide (38 mg) and triethylamine (304 mg) were added successively and the mixture was stirred in a sealed tube at 70° C. for 2 hours. After cooling, the reaction solution was poured into water, and the mixture was extracted with chloroform, dried over anhydrous magnesium sulfate, filtered and concentrated. The resulting residue was separated using silica gel column chromatography (chloroform:methanol=10:1) to obtain 347 mg (88.9%) of the desired product as a brown oil.
