To a mixture of methyl(6-hydroxy-4-methyl-1-benzothiophen-3-yl)acetate (150 mg) and THF (dry) (5 mL) were added (2-methyl-6-(trifluoromethyl)pyridin-3-yl)methanol (133 mg), tri-n-butylphosphine (0.204 mL) and ADDP (192 mg) at room temperature. The mixture was stirred at room temperature for 4 h. The insoluble material was removed by filtration, and the filtrate was concentrated in vacuo. The residue was purified by silica gel column chromatography (EtOAc/hexane) to give the title compound (238 mg).
