Procedure

A solution of (2-{7-[methyl(2-thienylsulfonyl)amino]-1H-indol-2-yl}-4,5-dihydro-1,3-thiazol-5-yl)acetic acid (200 mg), 2-methyl-6-nitrobenzoic acid anhydride (190 mg), 4-dimethylaminopyridine (56 mg), triethylamine (200 μL) and methanesulfonamide (46 mg) in acetonitrile (5 mL) was stirred at room temperature for 18 hr. 1N Hydrochloric acid was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The ethyl acetate layer was washed with saturated brine, dried (MgSO4), and concentrated. The obtained residue was subjected to silica gel column chromatography to give the title compound (76 mg, yield 33%) as white crystals from a fraction eluted with ethyl acetate. melting point 141° C.
