Reaction Steps

9.61 g of hydrazine monohydrate was added to an ethanol solution (500 ml) containing 15.06 g of 4-(2-methyl-4-phthalimidobutyl)-1-(3-hydroxycarbonylpropionyl)benzene, and the mixture was refluxed under heating for 2.5 hours. After cooling, precipitated crystal was collected by filtration and recrystallized from ethyl acetate to obtain 8.14 g of 6-[4-(4-amino-2-methylbutyl)phenyl]-4,5-dihydropyridazin-3(2H)-one.
