100 mg (0.29 mmol) of 2-[4-(5-chloro-2-cyanophenyl)-5-methoxy-2-oxopyridin-1(2H)-yl]butanoic acid (racemate) and 73 mg (0.43 mmol, 1.5 eq.) of 4-(1,2,4-oxadiazol-3-yl)aniline were reacted according to General Method 7. The crude product was purified by normal phase chromatography (mobile phase: dichloromethane/methanol 2-5% mixtures) and subsequently by preparative HPLC (water/acetonitrile/0.1% formic acid gradient). Yield: 81 mg (55% of theory)
