Procedure
A mixture of 4-amino-2-chlorobenzonitrile (5.0 g, 0.033 mol) and N-iodosuccinimide (8.28 g, 0.036 mol) in HOAc (35 mL) was stirred at RT overnight. A brown solid formed, which was collected by filtration, washed with hexanes, and dried in vacuo to afford 3.6 g (39%) of 4-amino-2-chloro-5-iodobenzonitrile (236) as a pale brown solid: MS (ESI) m/z=278.8 [M+1]+.
