Versuchsvorschrift

150 mg (0.43 mmol, 1.0 eq.) of 2-[4-(5-chloro-2-cyanophenyl)-5-methoxy-2-oxopyridin-1(2H)-yl]butanoic acid (racemate) and 152 mg (0.65 mmol, 1.5 eq.) of tert-butyl 2-fluoro-4-aminophenylcarboxylate were reacted according to General Method 5C. The crude product was purified by normal phase chromatography (mobile phase: cyclohexane/ethyl acetate 20%-50% mixtures). Yield: 250 mg (purity 93%, 99% of theory)
