63.0 mg (157 μmol) of 2-[4-(5-chloro-2-cyanophenyl)-5-methoxy-2-oxopyridin-1(2H)-yl]-4,4,4-trifluorobutanoic acid (racemate), 26.0 mg (157 μmol) of ethyl 4-aminobenzoate, 22.3 mg (157 μmol) of Oxima and 24.0 μl (157 μmol) of DIC in 1.6 ml of dimethylformamide were reacted according to General Method 5B. The reaction product was purified by preparative HPLC [column: Chromatorex C18, 10 μm, 125×30 mm, mobile phase: acetonitrile/0.05% formic acid gradient (0 to 3 min 10% acetonitrile, to 35 min 90% acetonitrile and a further 3 min 90% acetonitrile)]. Yield: 25.1 mg (28% of theory)
