Procedure

60 mmol of 4-amino-1,5-dimethyl-2-phenyl-1,2-dihydro-3H-pyrazol-3-one and 60 mmol of N,N-dimethylbenzene-1,3-diamine was dissolved in 300 ml of ice-water. This solution was admixed with 60 mmol of ferric chloride and 300 ml of saturated aqueous sodium chloride. Sodium perchlorate was added to saturation, and the mixture was left to stand for 30 minutes at zero degrees.
