실험 절차
6-(4-Benzylamino-3-nitro-phenyl)-5-methyl-4,5-dihydro-2H-pyridazin-3-one E-4.1′ (662 mg; 1.96 mmol) is solved in 200 ml THF, a scoop of Raney Nickel is then added. The mixture is placed in the hydrogenation apparatus and stirred at RT for 1.5 hours under 4 bar hydrogen pressure. The Raney Nickel is filtered off and the reaction solution evaporated to dryness.
