21 mg (38 μmol) of ethyl 4-({2-[4-(5-chloro-2-cyanophenyl)-5-methoxy-2-oxopyridin-1(2H)-yl]-4,4,4-trifluorobutanoyl}amino)benzoate (racemate) in 0.75 ml of methanol/water (4/1) were reacted with 25 mg (77 μmol) of caesium carbonate according to General Method 4. The crude product was purified by preparative HPLC [column: Chromatorex C18, 10 μm, 125 mm×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: 9 mg (46% of theory)
