A simple, economical, and efficient approach to the one‐pot synthesis of 3‐methyl‐4‐aryl‐2,4,5,7‐tetrahydropyrazolo[3,4‐b]pyridine‐6‐ones by multicomponent assembling of 5‐methylpyrazol‐3‐amine, aldehydes, and Meldrum's acid using mesoporous silica phenylsulfonic acid (SBA‐15‐Ph‐SO 3 H) as recyclable and heterogonous solid acid nanocatalyst has been described. This protocol has the advantages of high yields, wide application scope, and an environmental benign procedure.
