実験手順
Cyclohex-2-enesulfonyl-benzene (7) (10 g, 45 mmol) is dissolved in 450 ml of dry THF and cooled down to −20° C. Then 1.6 M BuLi in Hexane (30.9 ml, 49.5 mmol) is added and stirred for 15 min. After addition of benzyl 2-bromoethylether (8.5 ml, 54 mmol) the mixture is stirred for 1 h at 0° C. Then the mixture is evaporated to dryness. The residue is treated with ice/1M HCl and extracted twice with ether. The combined organic layers are dried over Na2SO4 and evaporated under educed pressure. The product is used in the next step without further purification.
