실험 절차

2.20 g (5.28 mmol) of 2-[4-(5-chloro-2-cyanophenyl)-5-methoxy-2-oxopyridin-1(2H)-yl]-3-[tetrahydro-2H-pyran-2-yl]propanoic acid (mixture of racemic diastereomers), 798 mg (5.28 mmol) of methyl 4-aminobenzoate, 750 mg (5.28 mmol) of Oxima and 822 μl (5.28 mmol) of DIC in 110 ml of dimethylformamide were reacted according to General Method 5B. The reaction mixture was purified by flash chromatography (80 g cartridge, 60 ml/min, cyclohexane/ethyl acetate gradient). Yield: 905 mg (31% of theory)
