PROCEDURE

实验过程

400 mg (734 μmol) of 3-(4-{[tert-butyl(dimethyl)silyl]oxy}cyclohexyl)-2-[4-(5-chloro-2-cyanophenyl)-5-methoxy-2-oxopyridin-1(2H)-yl]propanoic acid (mixture of two racemic diastereomers), 142 mg (734 μmol) of tert-butyl 4-aminobenzoate, 104 mg (734 μmol) of Oxima and 114 μl (734 μmol) of DIC in 7.3 ml of dimethylformamide were reacted according to General Method 5B. The crude product was purified by flash chromatography (40 g cartridge, 40 ml/min, cyclohexane/ethyl acetate gradient). Yield: 341 mg (64% of theory)
