5-BROMO-3-METHYL-BENZENE-1,2-DIAMINE Chemical Properties,Usage,Production

Uses

5-Bromo-3-methylbenzene-1,2-diamine is used as an intermediate in organic synthesis.

Synthesis

77811-44-0

76153-06-5

Step 1: Stannous chloride (SnCl2, 5.0 g, 26.1 mmol) was added to an ethanol (EtOH, 20 mL) suspension of 4-bromo-2-methyl-6-nitroaniline (2.0 g, 8.7 mmol). The reaction mixture was heated to reflux for 14 h, followed by cooling to room temperature and vacuum concentration. The residue was diluted with ethyl acetate (EtOAc, 100 mL) and partitioned between saturated aqueous sodium bicarbonate (NaHCO3) solution (200 mL) and water. The resulting slurry was filtered through a Celite pad and the wet filter cake was washed with ethyl acetate (3 x 50 mL). The filtrate was washed sequentially with saturated aqueous sodium bicarbonate, water, and brine, dried over anhydrous magnesium sulfate (MgSO4), filtered, and concentrated in vacuum to give 1.27 g (72% yield) of 5-bromo-3-methylbenzene-1,2-diamine (72) as a yellow oil: mass spectrum (ESI) m/z = 201.1 [M + 1]+.
