Versuchsvorschrift

This material was prepared according to the procedure used for SM-9, step 2 using 1-bromo-2,5-dichloro-3-nitrobenzene. Purification by flash chromatography (SiO2, 0-30% EtOAc in heptane) provided 3-bromo-2,5-dichloroaniline (24%): LCMS (m/z) 239.9 (MH+), tR=1.03 minutes; 1H NMR (400 MHz, CDCl3) δ 4.28 (br s, 2H) 6.71 (d, J=2.4 Hz, 1H) 7.02 (d, J=2.4 Hz, 1H).
