Procedure
69.0 mg (119 μmol) of ethyl 4-({2-[4-(5-chloro-2-cyanophenyl)-5-methoxy-2-oxopyridin-1(2H)-yl]-3-(4-methyltetrahydro-2H-pyran-4-yl)propanoyl}amino)benzoate (racemate) in 4.3 ml of ethanol/water (3/1) were reacted with 198 mg (609 μmol) of caesium carbonate according to General Method 4, giving the title compound after preparative HPLC [column: Chromatorex C18, 10 μm, 125 mm×30 mm, mobile phase: acetonitrile/0.1% formic acid gradient (0 to 3 min 10% acetonitrile, to 35 min 90% acetonitrile and a further 3 min 90% acetonitrile)]. Yield: 38 mg (57% of theory)
