Versuchsvorschrift

3.6 g (0.01 mol) of 2,2-dimethylpropionyl bromide 2,4,6-trichlorophenylhydrazone and 0.6 g (0.01 mol) of N-methylcyanamide were added to 50 ml of toluene. Then, 1.1 g (0.011 mol) of triethylamine was dropwise added under stirring at room temperature. After the dropwise addition, stirring was continued at the same temperature for further 1 hour. After washing the reaction mixture with water, the toluene layer was dried, and the solvent was distilled off. The residue was purified by silica gel column chromatography to obtain 2.8 g (yield: 85%) of 3-(tert-butyl)-5-(N-methylamino)-1-(2,4,6-trichlorophenyl)-1H-1,2,4-triazole as power having a melting point of from 165° to 166° C.
