실험 절차

2,3-Dimethylbenzotellurazolium trifluoromethanesulfonate (Example 30) (0.80 g, 0.002 mole) and 4-dimethylaminobenzaldehyde (0.30 g, 0.002 mole) were heated together in ethanol (about 30 ml), with one drop of piperidine present, to boiling and maintained at boiling for ten minutes. An intense red color developed. The dye separated as crystals on cooling. After overnight chilling they were isolated by filtration and recrystallized from ethanol, using diethyl ether to aid in reprecipitation. Yield 0.21 g (19% of theory).
