Tributylphosphine → Ethyl(6-((1-methyl-3-(trifluoromethyl)-1H-pyrazol-5-yl)methoxy)-1-benzothiophen-3-yl)acetate

Participants

Reaction Steps

To a mixture of tri-n-butylphosphine (0.165 mL), (1-methyl-3-(trifluoromethyl)-1H-pyrazol-5-yl)methanol (110 mg), ethyl(6-hydroxy-1-benzothiophen-3-yl)acetate (120 mg), and THF (5.0 mL) was added ADDP (167 mg) at room temperature. The mixture was stirred at room temperature under nitrogen atmosphere overnight. The mixture was concentrated. 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 (NH, EtOAc/hexane) and then silica gel column chromatography (EtOAc/hexane) to give the title compound (173 mg). The solid was crystallized from EtOH-hexane to give the title compound.
