Tributylphosphine → Methyl(7-fluoro-4-methyl-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 (0.338 mL), methyl(7-fluoro-6-hydroxy-4-methyl-1-benzothiophen-3-yl)acetate (131.3 mg), (1-methyl-3-(trifluoromethyl)-1H-pyrazol-5-yl)methanol (93 mg) and THF (4.0 mL) was added ADDP (284 mg) at room temperature. The mixture was stirred overnight at room temperature under nitrogen atmosphere. 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) to give the title compound (205.9 mg). The compound was crystallized from EtOAc-hexane.
