A simple and clean access to pyrazolo[3,4-d]thiazolo[3,2-a]pyrimidine derivatives using solvent-free and HSBM techniques through the multi-component reaction of 3-methyl-1-phenyl-1H-pyrazol-5-amine, 1-aryl-2-thiocyanatoethan-1-one and aromatic aldehydes is reported. Using 2-hydroxyethan-1-aminium acetate as an ionic liquid get the product in high yields.
