Versuchsvorschrift

3-Nitro-phenylamine (27.6 g, 0.2 mol) was dissolved in a mixture of H2O (40 mL) and 37% HCl (40 mL). A solution of NaNO2 (13.8 g, 0.2 mol) in H2O (60 mL) was added at 0° C., followed by the addition of SnCl2.H2O (135.5 g, 0.6 mol) in 37% HCl (100 mL) at that temperature. After stirring at 0° C. for 0.5 h, the solid was isolated via filtration and washed with water to give (3-nitro-phenyl)-hydrazine hydrochloride salt (B-4-a) (27.6 g, 73%).
