반응 단계
Sodium hydroxide solution (10%, 15 mL) was added slowly to a stirred suspension of (3-nitro-phenyl)-hydrazine hydrochloride salt (B-4-a) (1.89 g, 10 mmol) in ethanol (20 mL) until pH 6. Acetic acid (5 mL) was added to the mixture followed by propionaldehyde (0.7 g, 12 mmol). After stifling for 3 h at room temperature, the mixture was poured into ice-water and the resulting precipitate was isolated via filtration, washed with water and dried in air to obtain N-(3-nitro-phenyl)-N′-propylidene-hydrazine, which was used directly in the next step.
