反応手順

a Fluorescent Indo-Dansyl Analog: Compound 27z was synthesized by the method outlined in FIG. 4. Briefly, indomethacin was complexed with N-BOC butanediamine for 16 hours at room temperature in the presence of 1-ethyl-3-(3′-dimethylaminopropyl)carbodiimide hydrochloride (EDCl), 1-hydroxybenzotriazole (HOBt), dimethylaminopyridine (DMAP), N,N′-diisopropylethylamine (DIPEA), and N,N-dimethylformamide (DMF). A yellow solid corresponding to a percent yield of 72% was obtained. This solid was then dissolved in dichloromethane and treated with HCl (gas) for 2 hours at room temperature, producing N-(4-aminobutyl)-2-[1-(4-chlorobenzoyl)-5-methoxy-2-methyl-1H-indol-3-yl]acetamide hydrochloride as a brown solid (98% yield), which was reacted with triethylamine (TEA) in dichloromethane for 5 minutes at room temperature prior to the addition of dansyl chloride. Dansyl chloride was then added, and the reaction was allowed to continue for 16 hours at room temperature, which produced Compound 27z as a yellow solid in a yield of 77%. Compound 27z was characterized by NMR and mass spectroscopy (MS).
