実験手順

2-Chloro-4-fluorobenzenesulfonyl chloride (1.16 g; 5.0 mmol) was added to a cold solution (ice:water temperature) of 3-chloro-5-[2-(4-cyanophenyl)ethoxy]phenol (0.689 g; 2.5 mmol; from step (ii) above) in pyridine (8 mL). The temperature was allowed to rise (slowly) to ambient overnight. The mixture was re-cooled (ice:water temperature) and ice was added to the reaction flask. After stirring for 4 hours, the pyridine was removed in vacuo. CH2Cl2 was then added and the organic layer was washed with aqueous KHSO4 and water. Drying (MgSO4), evaporation of the solvent and purification by flash chromatography (SiO2; CH2Cl2) afforded 0.84 g (72%) of the sub-title compound.
