Procedure

To a solution of 1-[6-(5-{1-[4-(cyclopropylsulfonyl)phenyl]-2-(tetrahydro-2H-pyran-4-yl)ethyl}-1H-pyrrol-2-yl)pyridin-3-yl]ethane-1,2-diol (245 mg) in N,N-dimethylformamide (5 mL) were added N-(tert-butoxycarbonyl)glycine (86.0 mg), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (115 mg), 1-hydroxybenzotriazole (80.0 mg) and N-methylmorpholine (162 μL) under ice-cooling, and the mixture was stirred overnight at room temperature. The reaction mixture was diluted with ethyl acetate, washed with water and saturated brine, dried (MgSO4) and concentrated. The residue was subjected to silica gel column chromatography, and the title compound (110 mg, yield 34%) was obtained as a colorless amorphous solid from a fraction eluted with ethyl acetate-hexane (2:1, volume ratio). MS: 654 (MH+).
