## Abstract The synthesis of several __N__‐__tert__‐butoxycarbonyl(Boc)‐protected‐__N__‐substituted hydrazines has been accomplished. The use of these protected hydrazines in S~N~Ar substitutions leads to products in which the most nucleophilic nitrogen displaces the leaving group. Treatment of the
