Participants

Reaction Steps

To the mixture of (triphenylphosphanylidene)acetonitrile (19.8 g, 51.9 mmol) and NaOH (2.59 g, 64.9 mmol) in DCM (30 mL) and water (60 mL) was added 4-{[4-chloro-3-(trifluoromethyl)phenyl]oxy}benzaldehyde (13.0 g, 43.2 mmol)) at 0° C. It was stirred at rt for 4 h. Purification via a flash chromatography afforded the title compound as a white solid (12 g).
