実験手順

10 g (23 mmol) of ethyl 4′-hydroxy-3′-(5,5,8,8-tetramethyl-5,6,7,8-tetrahydronaphth-2-yl)biphenyl-4-carboxylate are dissolved in 400 ml of tetrahydrofuran. 9.2 g (35 mmol) of triphenylphosphine and 6.9 ml (35 mmol) of diisopropyl azodicarboxylate are added and the reaction medium is stirred at room temperature for 30 minutes. 2.8 ml (28 mmol) of 4-chlorobutanol are then added, and the medium is kept stirring for 12 hours, and then poured into 500 ml of water and extracted with ethyl acetate. The residue obtained is purified by chromatography on silica gel (eluent: 80/20 heptane/ethyl acetate). 8.9 g of ethyl 4′-(4-chlorobutoxy)-3′-(5,5,8,8-tetramethyl-5,6,7,8-tetrahydronaphth-2-yl)biphenyl-4-carboxylate are obtained in the form of a colorless oil (yield=73%).
