実験手順

To a mixture of 1-(4-(methylsulfonyl)phenyl)-4-(piperidin-4-yloxy)pyridin-2(1H)-one hydrochloric acid (154 mg, 0.40 mmol) and diisopropylethylamine (0.35 mL, 0.20 mmol) in CH2Cl2 (1.5 mL) at room temperature was added 4-bromophenyl chloroformate (prepared according to procedures described at Step B of Example 2 substituting 4-bromophenol for 1,1,1-trifluoro-2-propanol) in CH2Cl2 (1.0 mL). The resulting mixture was stirred at room temperature for 3 hrs, diluted with CH2Cl2 and washed with water and brine. The organic layer was dried (Na2SO4) and evaporated under reduced pressure. The crude product was purified by flash chromatography on silica gel (0-100% EtOAc/Hexanes) to give the title compound (159 mg, 73%) as a light yellow solid. MS (ESI) 547, 549 (M+H).
