| Abstract: | A series of 2 -aminobenzothiazolo-arylmethyl-2-naphthols were synthesized via three-component reaction of aromatic aldehyde, 2-aminobenzothiazole and 2-naphthol in ionic liquid of Hnmp]HSO4 under solvent-free conditions. The method provided several advantages such as milder conditions, shorter reaction time, high yields and environmentally benign procedure. Moreover, the catalyst could be recovered conveniently and reused for at least four times without evident loss of activity. The products were identified by 1H NMR, IR, MS techniques and elemental analysis. |
