実験手順

A suspension of 3-[bis(4-methoxybenzyl)amino]-6-(1-isopropyl-6-oxo-1,6-dihydro-3-pyridazinyl)-5-phenyl-2-pyrazinecarbonitrile (3.00 g) in a mixture of 2N aq. NaOH (30 ml) and dioxane (21 ml) was refluxed for 36 hours. After cooling, the mixture was extracted with EtOAc, dried over MgSO4, concentrated under reduced pressure and purified by column chromatography on silica gel eluting with a mixture of n-hexane and EtOAc (20:80 v/v) to give a solid. The solid was crystallized from a mixture of n-hexane and acetone to give 3-[bis(4-methoxybenzyl)amino]-6-(1-isopropyl-6-oxo-1,6-dihydro-3-pyridazinyl)-5-phenyl-2-pyrazinecarboxamide (2.56 g).
