実験手順

A 100-mL round-bottom flask fitted with a reflux condenser was charged with 3-(5-chloro-2,3,3-trimethyl-3H-pyrrolo[2,3-b]pyridin-7-ium-7-yl)propane-1-sulfonate (55, 500 mg), sodium 2,3,3-trimethyl-1-(3-sulfonatopropyl)-3H-indolium-5-sulfonate (4, 500 mg), (E)-N—((Z)-2-bromo-3-(phenylamino)allylidene)benzenaminium bromide (8, 100 mg), pyridine (1 mL), and acetic anhydride (10 mL) were added to the flask. The mixture was heated at 115° C. for 2 h, allowed to cool to room temperature, and diluted with ethyl ether (25 mL). The resulting dark blue dye precipitate was collected by filtration, dissolved in water (20 mL), and purified by preparative reverse-phase HPLC to afford the 9 as a blue powder (285 mg, 50%, UV 668 nm).
