실험 절차

70 mg (186 μmol) of 2-[4-(5-chloro-2-cyanophenyl)-5-methoxy-2-oxopyridin-1(2H)-yl]-4-methoxybutanoic acid (racemate), 27.7 mg (186 μmol, 1.0 eq.) of 5-aminobenzimidazolone, 26.4 mg (186 μmol) of Oxima and 28.9 μl (186 μmol) of DIC in 3.9 ml of dimethylformamide were reacted according to General Method 5. The crude product was purified by preparative HPLC (column: Chromatorex 125 mm×30 mm, 10 μm, mobile phase: water/0.1% formic acid and acetonitrile/0.1% formic acid, gradient 10% acetonitrile to 90% acetonitrile) and then subjected to basic extraction (aqueous sodium hydroxide solution/ethyl acetate). Yield: 44 mg (47% of theory)
