2,3-Diaminotoluene Usage And Synthesis
Chemical Propertiesbrown powder
UsesInducer of CYP1A activity, and possible mutagenic carcinogen.
General DescriptionThe antitumour activity of Pd(II) and Pt(II) new complexes with 2,3-diaminotoluene was studied. 2,3-Diaminotoluene induced CYP1A activity.
Synthesis
2-Methyl-6-nitroaniline

570-24-1

2,3-DIAMINOTOLUENE

2687-25-4

General procedure for the synthesis of 2,3-diaminotoluene from 2-methyl-6-nitroaniline: 4.0 g of 10% palladium-carbon catalyst (51.5% in water) was added to 200 ml of ethanol solution containing 8.50 g (55.9 mmol) of 2-methyl-6-nitroaniline. The reaction mixture was stirred at room temperature and atmospheric pressure in a hydrogen atmosphere for 4 hours. Upon completion of the reaction, the catalyst was removed by filtration and the solvent was subsequently removed by evaporation from the filtrate to afford 6.64 g (97% yield) of 2,3-diaminotoluene crude product in the form of black crystals. The product could be used directly in the subsequent reaction without further purification.1H-NMR (CDCl3) δ: 2.22 (3H, s), 3.35-3.40 (4H, m), 6.62-6.68 (3H, m).
