There are several known methods of protecting amines as their Boc derivatives. For less nucleophilic amines such as aryl amines these methods often give poor yields and are generally not satisfactory. Here, Boc aryl amines are obtained by first introducing two Boc groups followed by selective removal of one of them. This procedure works well for a number highly sterically hindered substrates as well as electron deficient and electron rich aryl amines.
