“…Many synthetic methods for formulating dihydro-pyrimidine compounds have been designated including classical methods, microwave irradiation and by using Lewis acids as well as protic acids in recent years ( XH Liu, Tan, & Weng, 2011;Lu & Bai, 2002;Ryabukhin, Plaskon, Ostapchuk, Volochnyuk, & Tolmachev, 2007;Schauble, Trauffer, Deshpande, & Evans, 2005;Wang et al, 2011). The sighting of a new and cheap catalyst for the preparation of dihydro pyrimidine in neutral and mild conditions with high yield is of prime importance.…”
