There total 4 articles about 1,2-Benzenediamine,N1-ethyl-4-methyl-(9CI) which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield:

ethyl-(4-methyl-2-nitrophenyl)amine (37637-58-4) → N1-ethyl-4-methyl-o-phenylenediamine (115835-41-1)

Guidance literature:

With palladium on activated charcoal; ethanol; Hydrogenation;

DOI:10.1021/ja01540a038

Reference yield:

toluene-4-sulfonic acid-(N-ethyl-4-methyl-2-nitro-anilide) (857245-62-6) → N1-ethyl-4-methyl-o-phenylenediamine (115835-41-1)

Guidance literature:

Multi-step reaction with 2 steps

1: H₂SO₄; acetic acid

2: palladium/charcoal; ethanol / Hydrogenation

With palladium on activated charcoal; ethanol; sulfuric acid; acetic acid;

DOI:10.1021/ja01540a038

Reference yield:

4-Methylacetanilide (103-89-9) → N1-ethyl-4-methyl-o-phenylenediamine (115835-41-1)

Guidance literature:

Multi-step reaction with 3 steps

1: nitric acid / 30 - 40 °C / man giesstin kaltes Wasser; das ausgeschiedene 3-Nitro-4-acetamino-toluol loest man in moeglichst wenig Alkohol und versetzt die siedende Loesung mit etwas mehr als 1 Mol_.-Gew_.Kalilauge

2: alcohol / 120 - 130 °C / man zieht das Produkt mit konz.Salzsaeure aus und faellt die Loesung mit Wasser; es ist vorteilhaft statt C₂H₅I C₂H₅Br anzuwenden

3: tin; hydrochloric acid

With hydrogenchloride; tin; ethanol; nitric acid;
