Participants

Reaction Steps

A solution of 392 mg (0.72 mmol) of methyl 4-[(4E)-5-[2-(4-bromobutoxy)phenyl]-3-(4-cyanobenzyl)pent-4-en-1-yl]benzoate in 10 ml of dry acetonitrile is mixed with 120 mg (1.08 mmol) of 4-fluorophenol and 148 mg (1.08 mmol) of anhydrous potassium carbonate and then heated under reflux for 12 h.
