SBA-15-SO3H with a high surface area and high acid content was readily synthesized, characterized, and effectively used in the synthesis of some new and known pyrido[2,3-d:6,5-d′]dipyrimidine derivatives by condensation reaction of 6-aminouracil and different aldehydes under solvent-free conditions. The catalyst was reused for 6 runs without significant loss of its activity. Short reaction times, high
