ABSTRACT:
2-Chloro and 2,6-dichloroanilines, optionally substituted in the 3-, 5-, and/or 6-position are prepared from the corresponding anilides by selective bromination, chlorination, reduction and hydrolysis. The selectivity of the process for introducing chlorines ortho to the amino group is very high.
