Procedure

50 mmol of 1,5-dimethyl-4-nitroso-2-phenyl-1,2-dihydro-3H-pyrazol-3-one was dissolved in a solution of 850 ml of acetic acid and 1250 ml of water. This solution was admixed with 50 mmol of 4-methylbenzene-1,3-diamine and stirring was continued for 2 h 30 min. Sodium perchlorate was added to saturation, and the mixture was left to stand for 30 minutes at zero degrees.

Workup

  1. waitthe mixture was left
