    Nickel‐catalyzed Buchwald–Hartwig amination of pyrimidin‐2‐yl tosylates with indole and benzimidazole was achieved using Ni(dppp)Cl2 as catalyst, yielding a variety of novel C2‐substituted pyrimidine derivatives in good yields. This reaction proved to be tolerant of various pyrimidin‐2‐yl tosylates bearing either electron‐donating or electron‐withdrawing groups as well as nucleophiles including indole, benzimidazole and 1,2,4‐triazole. Copyright © 2016 John Wiley & Sons, Ltd. A nickel‐catalyzed Buchwald–Hartwig amination of pyrimidin‐2‐yl tosylates with indole, benzimidazole and 1,2,4‐triazole is presented. The catalyst Ni(dppp)Cl2 proved to be tolerant of various pyrimidin‐2‐yl tosylates as well as nitrogen heterocyclic nucleophiles including indole, benzimidazole and 1,2,4‐triazole.
