Versuchsvorschrift
1-Hydroxy-4-phenylphthalazine (0.31 g, 1.5 mmol) in toluene (30 ml) is allowed to react with Lawesson's reagent (0.6 g, 1.5 mmol) and the mixture is stirred in an oil bath. (80-90° C.) for 1.5 hour until all starting material is used up. Evaporation of the solvent gives a yellow solid which is stirred with isopropyl ether. Filtration gives the title compound as a yellow solid which is recrystallized from hexane/THF/toluene:7.5/2.5/2.0 (0.3 g)
