PROCEDURE
实验过程
To 1-(3,5-dinitrobenzyl)-2,3,3-trimethyl-3H-indolium iodide (467 mg) was added 3,4-dihydroxy-3-cyclobuten-1,2-dione (110 mg), 1-(5-carboxypentyl)-2,3,3-trimethyl-3H-indolium iodide (354 mg), pyridine (4.5 ml), acetic acid (4.5 ml) and acetic anhydride (1 ml). The mixture was heated to reflux for 3 hours and the solvent then stripped using rotary evaporation. This crude material was subjected to silica flash column chromatography (eluted with MeOH/DCM). Fractions containing product were combined and stripped of solvent. The resulting material was further purified by reverse phase HPLC (CH3CN/H2O/TFA).
