실험 절차

9.8 gm of 5-methyl-6-[3-nitro-4-(4-methoxy-benzoylamino)-phenyl]-3-oxo-4,5-dihydro-2H-pyridazine were dissolved in 1000 ml of ethanol and hydrogenated for 24 hours at room temperature with a hydrogen pressure of 5 bar in the presence of 1 gm of 10% palladium charcoal. The obtained precipitate was suction filtered and used in the next step without removing the catalyst. A further fraction of the product can be obtained from the mother liquors.
