반응 단계
To 2-bromo-5-nitro-aniline (5 g) in conc hydrochloric acid (50 ml) at 0° C. was added a solution of sodium nitrite (1.45 g) in water (20 ml). After 1 h, a solution of tin dichloride (8.73 g) in conc hydrochloric acid (15 ml) was added. The reaction was stirred for 30 min at 0° C. and 1 h at room temperature. The resulting solid was filtered off and recrystalised from hot ethanol. Yield 2.9 g.
