The quaternary salts formed by reaction of tolyl sultone (2, 1, 3H‐benzoxathiole‐1, 1‐dioxide) with 2‐(1,3‐dioxolan‐2‐yl)‐ or 2‐(2‐methyl[1, 3]dioxolan‐2‐yl)pyridine may be cyclized in acid to afford the betaines derived from 7‐sulfo‐ and 7‐sulfo‐11‐methylacridizinium hydroxides. Similarly 1‐(1,3‐dioxolan‐2‐yl)isoquinoline may be converted to the betaine of 9‐sulfobenzo[a]acridizinium hydroxide. The sodium salt of 2‐(3′‐sulfobenzoyl)pyridine may be quaternized with benzyl bromide and the resulting betaine cgclized to afford the betaine of 11‐(3′‐sulfophenyl)acridizinium hydroxide.
