A small series of new 3,5‐dimethyl‐4‐(arylsulfanyl)pyrazoles have been synthesized in good to excellent yields by a grinding‐induced, sequential one‐pot three‐component reaction, of an equimolar mixture of 3‐chloro‐2,4‐pentanedione, differently substituted thiophenols, and hydrazine hydrate in the presence of piperidine under solvent‐free conditions.
