2,3-Diaminotoluene Chemical Properties, Uses, Production

Chemical Properties

brown powder

Uses

Inducer of CYP1A activity, and possible mutagenic carcinogen.

General Description

The antitumour activity of Pd(II) and Pt(II) new complexes with 2,3-diaminotoluene was studied. 2,3-Diaminotoluene induced CYP1A activity.

Synthesis

570-24-1

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).
