In this study, an acidic nicotine‐based ionic liquid supported on magnetic nanoparticles ([NicTC]HSO 4 @MNPs) was synthesized and characterized by different techniques. The activity of this catalyst was evaluated in a multi‐component reaction of 2‐aminobenzothiazole , aldehydes / dialdehydes and β‐ketoesters/1,3‐diketones to afford a series of novel mono ‐ and bis ‐4 H ‐pyrimido[2,1‐ b ]benzothiazole derivatives. In addition, mild reaction conditions, high yields, excellent selectivity as well as easy recovery and reusability of the catalyst, make this method an economic and environmentally‐benign process.
