実験手順

The mixture consisting of 2.5 g of 3-fluoro-4-nitrophenylhydrazine, 1.2 g of [1,2,3]triazine and 50 ml of ethanol was heated to reflux with stirring for 6 hours. After concentrating the reaction mixture under reduced pressure, the residue was worked up by column chromatography (solvent: 99:1 dichloromethane:methanol; silica gel).
