実験手順

780 mg (1.05 mmol) of methyl E-4-[5-[2-(4-tert-butylbenzyloxy)phenyl]-3-(3,5-difluoro-4-triisopropylsilanyloxybenzyl)pent-4-enyl]benzoate are introduced into 20 ml of THF at room temperature under argon, 2.11 ml (2.11 mmol) of a 1 M solution of tetra-n-butylammonium fluoride in THF are added, and the mixture is stirred at room temperature until reaction is complete. All the volatile components are then removed in vacuo. The resulting crude product is purified by preparative HPLC. 229 mg (37% of theory) of the title compound are obtained.
