Reaction Steps

Lithium chloride (593 mg, 14 mmol), bis(triphenylphosphine)palladium (II) dichloride (123 mg, 0.175 mmol) and 5-tributylstannyl-1-furan-2-carbaldehyde (2.02 mg, 5.25 mmol) were added to a suspension of trifluoromethanesulfonic acid 4-(1-{4-[3-(t-butyl-dimethyl-silanyloxy)-4,4-dimethyl-pentyl]-3-methyl-phenyl}-1-ethyl-propyl)-2-methyl-phenyl ester (Example 3-(5); 1.10 g, 1.75 mmol) in dimethoxyethane (5.3 mL), and the mixture was stirred at 60° C. for 15 hours. Water and ethyl acetate were added to the mixture. The organic layer was washed with brine, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was purified by silica gel chromatography (hexane only to hexane/ethyl acetate=90/1) to give the title compound (2404 mg, 24%).
