Reaction Steps

To a solution of 2-bromo-4-nitrotoluene (50 g, 0.231 mol in ethylacetate (330 mL) and Ethanol (150 mL) was added Tin(II)chloride dihydrate (208 g, 0.924 mol) portionwise. The reaction mixture was stirred at room temperature overnight. The solution was then treated with potassium carbonate until pH=7 and filtered over celite. The filtrate was washed with water, aqueous NaHCO3, water and brine, dried (Mg2SO4), filtered and evaporated to give 42.71 g (100%) of 3-bromo-4-methylaniline. 1H NMR (300 MHz; CDCl3): 2.27 (s, 3 H), 3.57 (br s, 2 H), 6.54 (dd, J=2.7 Hz and 8.1 Hz, 1 H), 6.90 (d, J=2.1 Hz, 1 H), 6.98 (d, J=8.1 H).
