An efficient base-catalyzed synthesis of dihydropyrimidines and N-acetyl pyrazoles is reported using 1-(2-aminoethyl)piperazine-modified nano-NaY zeolite (ZeSi–AP) under mild and green conditions. The structure of the catalyst was identified by using FT-IR, XRD, TGA, DTA, DLS, SEM, TEM, and elemental analyses. This heterogeneous catalyst has many benefits, such as a simple work-up procedure, high product yield, and it is easily regenerated and reused at least for four cycles without losing its activity.
