Reaction Steps
980 mg of 5-nitro-phthalazin-1-one (Example 66) and 100 mg of palladium on activated carbon are suspended in 50 ml of ethyl acetate and 1 ml of triethylamine, and it is hydrogenated with hydrogen under normal pressure. It is filtered through diatomaceous earth, and the solvent is removed in a vacuum. 830 g of 5-amino-phthalazin-1-one as a solid is obtained as a crude product.
