Participants

Reaction Steps

A solution of (4-{[4-chloro-3-(trifluoromethyl)phenyl]oxy}phenyl)methanol (200 mg, 0.661 mmol) in thionyl chloride (0.5 mL, 6.85 mmol) was stirred at rt for 1 h. Then the excess thionyl chloride was removed under vacuum to afford the title product (200 mg) as a yellow oil, which was used in the next reaction without purification.
