실험 절차

To a solution of 4-[1-{5-[5-(hydroxymethyl)-1,3-thiazol-2-yl]-1H-pyrrol-2-yl}-2-(tetrahydro-2H-pyran-4-yl)ethyl]benzoic acid (200 mg) in N,N-dimethylformamide (5 mL) were added 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (140 mg), 1-hydroxybenzotriazole (100 mg) and N-methylmorpholine (160 μL), and the mixture was stirred for 1% hr. To the reaction mixture was added N-methoxymethanamine hydrochloride (60.0 mg), and the mixture was stirred overnight at room temperature. The reaction mixture was diluted with ethyl acetate and washed with 1M hydrochloric acid. The ethyl acetate layer was washed with saturated aqueous sodium hydrogen carbonate and saturated brine, dried (MgSO4) and concentrated. The residue was subjected to silica gel column chromatography, and the title compound (92.0 mg, yield 42%) was obtained as a pale-yellow amorphous solid from a fraction eluted with ethyl acetate-methanol (19:1, volume ratio). MS: 456 (MH+).
