Yield:102170-56-9 99%
Reaction Conditions:
with bromine;acetic acid at 20; for 1.16667 h;
Steps:
A Step A: 2-Bromo-6-rnethyl-4-nitroaniiine.
To a suspension of 2-methyl-4-nitroaniline (10.0 g, 65.7mrnol) in glacial acetic acid (100 rnL) at 20 °C was added bromine (3.4 mL, 66 rnmoi) dropwiseover 40 mm. The mixture was stirred at 20 °C for another 30 mm. Then water (100 rnL) was added, and the resulting precipitate was collected by filtration and dried in vaeuo at 80 °C for 6 h to yield the title compound (14.1 g, 99%) as a yellow solid. MS (ESi): mass calcd. for C7HBrN2O2 23 0.0, m/z found 231 [M+Hft. ‘H NMR (300 MHz, DMSO-d6) ? 8.13 (d, J = 2.2 Hz, iH), 7.89 (d, J= 1.5 Hz, IH), 6.48 (s, 2H), 2.22 (s, 3H).
