実験手順

2.68 g (10 mmol) of 6-(4-chloro-3-nitro-phenyl)-4,5-dihydro-5-methyl-3(2H)-pyridazinone and 2.81 g (10 mmol) of 4-phthalimidomethyl-piperidine hydrochloride are suspended in 30 ml of dioxane. After the addition of 2.8 ml (20 mmol) of triethylamine, the mixture is boiled under reflux for 4 hours. After it has cooled to room temperature, the solution is filtered from the residue and concentrated by evaporation under vacuum. After recrystallization of the solid residue from acetonitrile, 3.76 g (79%) of an orange yellow solid, m.p. 256°-258° C., are obtained.
