الإجراء التجريبي

an Indo-Sulfathiazole Analog: Compound 27j was synthesized by the method outlined in FIG. 1. Briefly, Compound 27j was synthesized by first complexing succinic anhydride with sulfathiazole by reacting these compounds at room temperature for 6 hours in tetrahydrofuran (THF) in the presence of triethylamine (TEA) to produce succinylsulfathiazole as a white solid (67% yield). The succinylsulfathiazole was then reacted for 2 hours at room temperature with O—(N-succinimidyl)-1,1,3,3-tetramethyluronium tetrafluoroborate (TSTU) in dichloromethane in the presence of TEA to produce the corresponding succinimidyl ester, which was reacted with 1-(4-aminobutyl)-2-{1-(4-chlorobenzoyl)-5-methoxy-2-methyl-1H-indol-3-yl}acetamide in dichloromethane in the presence of TEA at room temperature for 16 hours to produce Compound 27j as a yellow gummy mass (45% yield). Compound 27j was characterized by NMR, two-dimensional NMR, and mass spectroscopy.
