実験手順

To a solution of 4-bromopyridine-3-carbaldehyde (2.50 g, 13.4 mmol) in ethanol (25 mL) and water (5 mL) was added 4-fluorophenyhydrazine hydrochloride (2.38 g, 14.6 mmol) (mixture turned a deep red) followed by sodium acetate (3.7 g, 27 mmol) in 5 mL of water (mixture turned a bright yellow). The mixture was warmed at 50° C. for 30 minutes to afford an orange precipitate. The mixture was cooled and diluted with water (50 mL) and the solid was collected by filtration. The filter cake was washed with water and dried to afford N-[1-(4-bromopyridin-3-yl)-meth-(E)-ylidene]-N′-(4-fluorophenyl)-hydrazine.
