Versuchsvorschrift

To a mixture of 3.88 g of 4-(2-hydroxyethyl)benzaldehyde, 6.7 g of 2,6-dichloro-4-(3,3-dichloro-2-propenyloxy)phenol, 100 ml of tetrahydrofuran, and 6.0 g of triphenylphosphine was added dropwise a solution of 4.7 g of diisopropyl azodicarboxylate dissolved in 20 ml of tetrahydrofuran at the ice temperature over 1 hour. After completion of the addition, the reaction mixture was stirred at room temperature for 24 hours, and concentrated under reduced pressure. The residue was subjected to silica gel chromatography, which afforded 6.63 g (yield, 69%) of 4-(2-(2,6-dichloro-4-(3,3-dichloro-2-propenyloxy)phenoxy)ethyl)benzaldehyde, m.p., 54.2° C.
