ionic liquids such as [BMIM][BF4] and [BMIM][PF6] are excellent media for the N-alkylation of poorly reactive acridine esters with 1,3-propane sultone. Advantages include a significant reduction in the amount of toxic 1,3-propane sultone needed for good conversion to product, and minimal formation of polysulfonated products. The alkylation reaction in ionic liquids is amenable to scale-up for the synthesis

A method is provided for N-alkylation of acridine compounds by reduction of acridines to corresponding acridans to improve the reactivity of the acridine nitrogen, and subsequent N-alkylation of the acridans in ionic liquid solvents to provide the corresponding acridinium compounds in high yield. This inventive process improves chemical conversion, and does not require the use of highly toxic alkylating agents, such as 1,3-propane sultone.
