실험 절차

To 2,3,5,6-tetrafluoro-4-[(2,2-dimethyidioxolan-4-yl)methoxy]pyridine (3.2 g, 11 mmol) in CH3CN (20 mL) was added Cs2CO3 (3.8 g, 12 mmol) and 3-hydroxy-4-(benzyloxy)benzonitrile (2.5 g, 11 mmol). After stirring for 24 hours the reaction was partitioned with water and ethyl acetate. The layers were separated, washed with water and brine, dried (Na2SO4), and the solvent was removed in vacuo. The residue was triturated with hexane/ethyl acetate (1/1) and the resulting solid was collected by filtration to give 3-[[3,5,6-trifluoro-4-[(2,2-dimethyldioxolan-4-yl)methoxy]pyridin-2-yl]oxy]-4-(benzyloxy)benzonitrile (3.0 g).
