A well-defined Zn(II)-complex catalyzes a sustainable and eco-friendly N-alkylation of various amines by alcohols in very good yields. The method shows wide functional group tolerance and produces the precursors in high yields for the marketed drugs tripelennamine and thonzonium bromide in gram-scale reactions.
