Using a recyclable catalyst, facile synthesis of pyrimidine derivatives (4a-e) is attributed through the one-pot multi-component reaction of 2-amino benzimidazole (1) substituted aromatic aldehydes (2a-e) with malononitrile (3) under ultrasonic irradiations. Synthesized derivatives might help society in getting more active pharmaceutical constituents. In this present work, series of substituted pyrimidine (4a-e) were synthesized and confirmed with different spectra characterization methods. The ZnCr2O4 nano-particles play a vital role in eco-friendly, highly efficient, recyclable heterogeneous nanocatalyst. Furthermore, synthesized pyrimidine derivatives showed significant biological activities. Advantages of this handy route are less reaction time, simple isolation, and highly yielded products.
