In this, a three-component reaction for the preparation of novel tetrazolo[1,5-a]pyrimidine-6-carboxamide derivatives from N,N'-(sulfonylbis(1,4-phenylene))bis(3-oxobutanamide), aldehydes and 1H-tetrazol-5-amine is reported. The application of FeO@SiO-(PP)(HSO) (A) as a catalyst afforded the desired products (a-a) in high yields in DMF as solvent as well as under solvent-free conditions.
