実験手順

1,4-Dichlorobutene (750 g; 5 mol) was added to a stirred suspension of 4-cyanophenol (119.12 g; 1 mol) and K2CO3 (345 g; 2.5 mol) in MeCN (1000 mL) and the reaction mixture was refluxed for 4 h. The reaction mixture was filtered and concentrated. The residue was dissolved in di-iso-propyl ether (2000 mL) and after 24 h the precipitate was filtered off. The filtrate was concentrated giving the sub-title compound as a yellow oil which solidified upon standing (186 g; 0.89 mol).
