実験手順

a Fluorescent Indo-Coumarinyl Analog: Compound 27cc, N-{2-(Coumarin-3-carboxylamido)ethyl}-2-{1-(4-chlorobenzoyl)-5-methoxy-2-methyl-1H-indol-3-yl}acetamide, was synthesized by the method depicted in FIG. 6. Briefly, indomethacin was complexed with tert-Butyl-2-aminoethylcarbamate for 16 hours at room temperature in the presence of 1-ethyl-3-(3′-dimethylaminopropyl)carbodiimide hydrochloride (EDCl), 1-hydroxybenzotriazole (HOBt), N,N-diisopropylethylamine (DIPEA), and N,N-dimethylformamide (DMF). A yellow solid of tert-Butyl 2-[2-{1-(4-chlorobenzoyl)-5-methoxy-2-methyl-1H-indol-3-yl}acetamido]ethylcarbamate was produced as a yellow solid at 75% yield. This product was then dissolved in dichloromethane and treated with HCl (gas) for 2 hours at room temperature, producing N-(2-Aminoethyl)-2-{1-(4-chlorobenzoyl)-5-methoxy-2-methyl-1H-indol-3-yl}acetamide hydrochloride as a brown solid with a yield of 98%, which was reacted with N,N-diisopropylethylamine (DIPEA) in dichloromethane for 5 minutes at room temperature prior to the addition of Coumarin-3-carboxylic acid, 1-ethyl-3-(3′-dimethylaminopropyl)carbodiimide hydrochloride (EDCl), 1-hydroxybenzotriazole (HOBt), and N,N-diisopropylethylamine (DIPEA) in dichloromethane. The reaction proceeded for 16 hours at room temperature and produced Compound 27cc as a yellow solid (35% yield).
