Participants

Reaction Steps

A solution of 3,3-bis(4-fluorophenyl)-2-(tetrazol-1-yl)2-propenol (108 mg, 0.34 mmol), triphenylphosphine (118 mg, 0.45 mmol) and N-bromosuccinimide (74 mg, 0.42 mmol) in tetrahydrofuran (5 mL) was stirred in an inert atmosphere for a period of 1.5 hours. The suspension (triphenylphosphine oxide precipitate) was diluted with hexanes (25 mL) and the suspension was filtered. The filtrate was concentrated under reduced pressure and the semi-crystalline solid was filtered through a short silica gel column eluted with 5-10% ethyl acetate in hexanes. The title compound, 108 mg.(84%), was obtained after removal of solvents under reduced pressure.
