Participants

Reaction Steps

To a solution of 2′-fluoro-5′-methoxy-2-(5-(trifluoromethyl)-1,3,4-thiadiazol-2-yl)-[1,1′-biphenyl]-4-ol (195 mg), ethyl 3-cyclopropyl-3-(3-(hydroxymethyl)phenyl)propanoate (157 mg) and tributylphosphine (213 mg) in THF (5.0 mL) was added ADDP (226 mg) at room temperature, and the mixture was stirred at room temperature for 3 hr. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (298 mg) as a pale-yellow oil.
