## Abstract ^1^H NMR measurements of __N__‐substituted picramides in dimethyl sulphoxide‐methanol containing sodium methoxide show that the two major modes of 1:1 interaction involve transfer of an amino proton to give the conjugate base or methoxide attack at the 3‐position to give a σ‐adduct. The
