Reaction Steps
To a solution of 5-difluoromethoxy-2-nitrobenzaldehyde (238 mg) and carbon tetrabromide (545 mg) in dichloromethane (5.4 mL) was added dropwise a solution of triphenylphosphine (863 mg) in dichloromethane (3.6 mL) under cooling with ice. The mixture was gradually warmed to room temperature and stirred for 6 hours. The reaction mixture was concentrated under reduced pressure. The residue was suspended in diethyl ether and this resulting mixture was stirred at room temperature for 16 hours. The precipitate was removed by filtration through celite (registered trademark) and washed with diethyl ether. The filtrate was concentrated under reduced pressure to obtain the title compound (536 mg).
