実験手順
A solution of 4-hydroxy-3-methoxy-2-nitro-benzaldehyde (1.6 g) in ethanol (15 ml) was added to a suspension of (R)-6-(4-hydrazino-phenyl)-5-methyl-4,5-dihydro-2H-pyridazin-3-one (1.75 g) in ethanol (20 ml) and the resulting mixture refluxed for two hours. The resulting crystals were filtered at room temperature and washed with ethanol. Yield 2.37 g. HPLC: purity 99.4%, optical purity 99.8%.
