Versuchsvorschrift

Into a 2000 mL 3-necked flask was placed a solution of tert-butyl 3-(4-bromophenyl)-4H-1,2,4-triazole-4-carboxylate (80.0 g, 247 mmol) in CH2Cl2 (800 mL). To the mixture was added TFA (400 mL). The resulting solution was stirred at room temperature for 1 h. The reaction was evaporated to provide 3-(4-bromophenyl)-1H-1,2,4-triazole as a white solid.
