An efficient and diversity oriented one-pot three component sequential synthetic method has been presented for the synthesis of 3-benzothiazolyl-2-styrylquinazolin-4(3H)-ones. The synthetic method involves the reaction of 3,1-benzoxazinone with 2-aminobenzothiazole and subsequently with aromatic aldehyde using SO3H-functionalized ionic liquids (SFILs) as solvent/ catalyst.
