Potassium cyanate → HCID 178441880, compound

Participants

Reaction Steps

6.3 g (0.02 mol) of 2,2-dimethylpropionyl chloride 2,4,6-trichlorophenylhydrazone was dissolved in 50 ml of ethanol. Then, a solution of 3.2 g (0.04 mol) of potassium cyanate in 30 ml of water, was dropwise added thereto under stirring at room temperature. After completion of the dropwise addition, stirring was continued at the same temperature for further 0.5 hour. The precipitated crystals were collected by filtration and washed with n-hexane to obtain 6.1 g (yield: 95.3%) of 5-hydroxy-3-(tert-butyl)-1-(2,4,6-trichlorophenyl)-1H-1,2,4-triazole as white powder having a melting point of from 272° to 274° C.
