실험 절차

To a suspension of 2-methyl-4-(4-nitrophenyl)-1-(2H)-phthalazinone (3.0 g, 10.7 mmol) in ethanol (150 mL) under N2 was added 10% Pd/C (0.75 g). The mixture was hydrogenated on a Parr hydrogenator at 50 psi for 2 hours, the catalyst was removed by filtration and the solvent was removed in vacuo to afford 2.67 g (97%) of 2-methyl-4-(4-aminophenyl)-1-(2H)-phthalazinone as a yellow solid.
