Potassium Carbonate → Methyl 4-[(4E)-3-(4-cyanobenzyl)-5-(2-{4-[4-(trifluoromethyl)phenoxy]butoxy}phenyl)pent-4-en-1-yl]benzoate

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 174 mg (1.08 mmol) of 4-trifluoromethylphenol and 148 mg (1.08 mmol) of anhydrous potassium carbonate and then heated under reflux for 12 h. The mixture is subsequently filtered, and the filtrate is evaporated to dryness. 450 mg (0.61 mmol, purity 86%, 86% of theory) of a yellowish oil are isolated.
