Reaction Steps

1-[(1,3-Dioxolan-2-yl)methyloxy]-4-iodobenzene (36.3 g) and trimethylsilylacetylene (50.0 g) were reacted in the presence of bistriphenylphosphinepalladium dichloride (2.50 g) and cuprous iodide (1.25 g), in triethylamine (140 ml) and pyridine (70 ml) at 60° C. for 2 hr. The reaction solution was partitioned between ethyl acetate and water. The resulting organic layer was washed with water, dried and concentrated. The resulting residue was dissolved in methanol and treated with 2N sodium hydroxide, to give 20.1 g of the title compound.
