Procedure

A mixture of 1-(4-methoxybenzyl)-2-(1,3-dioxolan-2-yl)pyridinium chloride (15 g, 0.049 mol) in 300 g of polyphosphoric acid was allowed to react at 120° C. for 3 hours. The reaction mixture was poured onto ice with stirring. The mixture was neutralized with dibasic sodium phosphate and an aqueous solution of lithium perchlorate (1.1 equiv.) was added. The precipitated solid was filtered and dried to yield 9-methoxybenzo [b]quinolizinium perchlorate (Formula VII: R2 =OCH3 ; R3 =R4 =H; X- =ClO4-), as a yellow solid.
