Procedure
To an ice-cooled and stirred mixture of methylamine hydrochloride (35 mg) and triethylamine (0.072 mL) in N,N-dimethylformamide (7 mL) were added {2-[6-fluoro-7-(2-methoxyethoxy)-5-{[6-(methylsulfonyl)pyridin-3-yl]oxy}-1H-indol-2-yl]-4,5-dihydro-1,3-thiazol-5-yl}acetic acid (135 mg), 1-hydroxybenzotriazole (70 mg) and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (100 mg). After stirring at 4° C. to room temperature for 15 h, the reaction mixture was partitioned between ethyl acetate and water. The organic layer was washed successively with aqueous sodium hydrogen carbonate solution and brine, dried (MgSO4), filtered, and concentrated to give colorless crystals, which were recrystallized from tetrahydrofuran-ethyl acetate to give the title compound (109 mg, 79%) as colorless crystals. MS 537 (MH+). mp 151-152° C.
