Versuchsvorschrift

The product solution from Example 1 was cooled to 0°C. and mixed with 20 ml. of isopropyl alcohol and 2 ml. of hydrazine. The mixture was stirred for 10 minutes, and was then warmed to room temperature and stirred for 15 hours. The product was then collected by filtration. The yield was 6.0 g. of 3,5-diphenyl-4(1H)-pyridazinone, m.p. 328°-32°C., which was identified by infrared and nuclear magnetic resonance analysis.
