Reaction Steps

To a stirring mixture of 6,6-dimethyl-5-((1E,3E)-4-(N-phenylacetamido)buta-1,3-dienyl)-1,2,3,6-tetrahydropyrrolo[3,2,1-ij]quinolinium-7-sulfonate and 6-(5-carboxypentyl)-5,6-dimethyl-1,2,3,6-tetrahydropyrrolo[3,2,1-ij]quinolinium-7-sulfonate in 5 mL acetic anhydride was added 5 mL pyridine. The reaction was heated to 110° C. for 2 hours. After cooling to room temperature the product was precipitated with ethyl acetate, washed with Et2O, and isolated by vacuum filtration. The final product was purified by reverse-phase HPLC yielding a blue solid. MS m/z calculated for C36H43N2O8S2 (M+H): 695.25. Found 695.3 (M+H, ESI+).
