الإجراء التجريبي

To 1-(5-carboxypentyl)-4,5,6,7-tetrafluoro-3-methyl-3-(4-sulfobutyl)-3H-indolium (24 mg) was added N-[5-(phenylamino)-2,4-pentadienylidene monohydrochloride (13 mg), acetic anhydride (4 ml) and acetic acid (2 ml). This mixture was heated to 120° C. for 1 hour 45 minutes after which time it was cooled to room temperature. This crude reaction mixture (ca. 5 mg/ml product) was used without purification as further described.
