Reaction Steps

A solution of 2-bromoaniline (22.0 g, 12.8 mmol), acetic anhydride (13.06 g, 12.8 mmol) and a catalytic amount of DMAP in CH2Cl2 (100 mL) was stirred at 0° C. The mixture was slowly warmed to room temperature and stirred overnight. The reaction mixture was washed with saturated aqueous NaHCO3 solution and concentrated. The residue was triturated with hexanes/CH2Cl2, the solid was filtered and rinsed with hexanes to give aa (25.4 g, 92.8%). HPLC Rt=1.523 min.
