Procedure

To a solution of 6-(5-{1-[4-(cyclopropylsulfonyl)phenyl]-2-(tetrahydro-2H-pyran-4-yl)ethyl}-1H-pyrrol-2-yl)pyridine-3-carboxylic acid (0.168 g) in N,N-dimethylformamide (5 mL) were added cyclopropylamine (0.036 mL), triethylamine (0.146 mL), N-[3-(dimethylamino)propyl]-N′-ethylcarbodiimide hydrochloride (102 mg) and 1-hydroxybenzotriazole (81 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 extract was washed successively with water and saturated brine, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was purified by basic silica gel column chromatography (ethyl acetate:hexane=30:70-100:30, volume ratio), and recrystallized from hexane-ethyl acetate to give the title compound (0.106 g, yield 58%) as colorless crystals. MS: 520 (MH+). melting point 134-136° C.
