Reaction Steps

150 mg (0.43 mmol) of 2-[4-(5-chloro-2-cyanophenyl)-5-methoxy-2-oxopyridin-1(2H)-yl]butanoic acid (racemate) and 154 mg (0.61 mmol, 1.4 eq.) of tert-butyl 4-amino-2,5-difluorobenzoate were reacted according to General Method 5B. The crude product was purified by normal phase chromatography (mobile phase: cyclohexane/ethyl acetate 20-40% mixtures). Yield: 180 mg (71% of theory)
