Nitro-aminobenzene compounds by usualnNitration of one on the amino group with a protective groupnprovided aminobenzene compound are availablenproduced purely by protecting the amino groupnNitro-aminobenzene compound first isolated, thenProtective group is split off using sulfuric acid, then thensulfate salt of nitro obtained from the hydrolysisnaminobenzene compound in the form of pure, crystallinenSeparates sulfates from the reaction mixture and isolatednand from this, if desired, the free nitro-aminobenzenenPure connection wins. |
