실험 절차

115 mg (285 μmol) of 2-[4-(5-chloro-2-cyanophenyl)-5-methoxy-2-oxopyridin-1(2H)-yl]-3-(3-methyloxetan-3-yl)propanoic acid (racemate), 51 mg (285 μmol) of allyl 4-aminobenzoate, 40.6 mg (285 μmol) of Oxima and 45 μl (0.29 mmol) of DIC in 2 ml of dimethylformamide were reacted according to General Method 5B. Preparative HPLC (acetonitrile/water gradient) gave the title compound. Yield: 25 mg (16% of theory)
