The major advantages of the present method are simple experimentation, use of inexpensive and eco-friendly reusable catalyst with good yields and short reaction times.}, number={2}, journal={Iranian Journal of Catalysis}, publisher={OICC Press}, author={Azimi, Seyyedeh Cobra}, year={2024}, month={Feb.}, keywords={3-dimethyluracil, 5-Amino-3-methyl-1-phenypyrazole, Cellulose sulfuric acid, Solvent-free, 6-Amino-1} }
