Reaction Steps

A solution of 1.3 g (2.19 mmol) of methyl E4-[3-(3,5-difluoro-4-triisopropylsilanyloxybenzyl)-5-(2-hydroxyphenyl)pent-4-enyl]benzoate in 20 ml of dry acetonitrile is mixed with 600 mg (2.62 mmol) of 4-tert-butylbenzyl bromide and 450 mg (3.28 mmol) of anhydrous potassium carbonate and heated under reflux for 12 hours. The mixture is then concentrated to dryness. The residue is taken up in ethyl acetate, washed with water and saturated sodium chloride solution, dried over sodium sulfate and concentrated. The resulting crude product is purified by preparative HPLC. 780 mg (48% of theory) of a colorless oil are obtained.
