TL;DR: In this paper, the presence of electron-releasing substituents on the aromatic ring of anilides, although necessary for the Vilsmeier-Haack cyclization to quinolines to proceed efficiently, can cause failure of the expected cyclization, leading to (Z) N,N-dimethylformamidines through an alternative course.
