실험 절차

To a mixture of tri-n-butylphosphine (0.196 mL), (2-methyl-6-(trifluoromethyl)pyridin-3-yl)methanol (105 mg), methyl(6-hydroxy-4,7-dimethyl-1-benzothiophen-3-yl)acetate (130.9 mg) and THF (5.0 mL) was added ADDP (198 mg) at room temperature. The mixture was stirred at room temperature overnight under nitrogen atmosphere. The mixture was concentrated in vacuo. To the residue was added IPE, and the precipitate was filtered off. The filtrate was concentrated in vacuo. The residue was purified by silica gel column chromatography (EtOAc/hexane) to give the title compound (159 mg) as solid. The solid was crystallized from EtOAc-hexane.
