実験手順

To a mixture of tri-n-butylphosphine (0.793 mL), (1-methyl-3-(trifluoromethyl)-1H-pyrazol-5-yl)methanol (187 mg), methyl(4-fluoro-6-hydroxy-1-benzothiophen-3-yl)acetate (250 mg) and THF (dry) (15 mL) was added ADDP (801 mg) at room temperature. The mixture was stirred at room temperature for 2 h and then concentrated in vacuo. To the residue was added IPE and the insoluble materials were removed by filtration. The filtrate was concentrated in vacuo. The residue was purified by silica gel column chromatography (NH, EtOAc/hexane) and silica gel column chrothatography (EtOAc/hexane) to give the title compound (310 mg). The crystals were recrystallized from acetone-hexane.
