Reaction Steps

To a solution of 5-{1-[4-(cyclopropylsulfonyl)phenyl]-2-(tetrahydro-2H-pyran-4-yl)ethyl}-1H-pyrrole-2-carboxylic acid (1.3 g) in N,N-dimethylformamide (15 mL) were added 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (980 mg) and 1-hydroxybenzotriazole ammonium salt (926 mg), and the mixture was stirred at room temperature for 3 days. Water 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 residue was subjected to silica gel column chromatography, and the title compound (910 mg, yield 70%) was obtained as a colorless amorphous solid from a fraction eluted with ethyl acetate. MS: 403 (MH+).
