The base‐catalyzed addition of acetylenes to the C=N bond has been developed. The reaction proceeds smoothly in the KOBut/DMSO superbase system, which allows the activated ethynide anions in sufficient concentrations to be generated. The synthesis opens a simple transition metal‐free access to large series of acetylenic amines, valuable building blocks and precursors for drug design.
