continuous‐flow synthesis of substituted pyrazolederivatives has been developed via the formation of vinylidene keto esters as key intermediates. Heterogeneous Ni2+‐montmorillonite was found to be an efficient catalyst for orthoester condensation of 1,3‐dicarbonyls under flow conditions. The intermediate reacted with methylhydrazine to afford pyrazolederivatives, for which suitable selection of a solvent
