Reaction Steps

87 mg (0.25 mmol) of 2-[4-(5-chloro-2-cyanophenyl)-5-methoxy-2-oxopyridin-1(2H)-yl]butanoic acid (racemate) and 56 mg (0.28 mmol, 1.1 eq.) of ethyl 5-amino-1H-indole-2-carboxylate were reacted according to General Method 5A. The crude product was purified by preparative HPLC (Reprosil C18, water/acetonitrile gradient). Yield: 94 mg (70% of theory)
