反応手順
(3-Nitro-phenyl)-hydrazine hydrochloride salt (B-4-a) (30.2 g, 0.16 mol) and 2-oxo-propionic acid ethyl ester (22.3 g, 0.19 mol) was dissolved in ethanol (300 mL). The mixture was stirred at room temperature for 4 h. The solvent was evaporated under reduced pressure to give 2-[(3-nitro-phenyl)-hydrazono]-propionic acid ethyl ester, which was used directly in the next step.
