Procedure

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 (270 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 (215 μL), and the mixture was stirred for 1 hr. To the reaction mixture was added cyclopropylamine (50 μL), and the mixture was stirred overnight at room temperature. The reaction mixture was diluted with ethyl acetate and washed with 1M hydrochloric acid. The obtained aqueous layer was neutralized with 1M aqueous sodium hydroxide solution, and the mixture was extracted with ethyl acetate. The ethyl acetate layer was washed with saturated brine, dried (MgSO4) and concentrated. The residue was subjected to silica gel column chromatography, and the title compound (210 mg, yield 71%) was obtained as a pale-yellow amorphous solid from a fraction eluted with ethyl acetate. MS: 452 (MH+).
