実験手順

In two batches, a total of 242 mg (0.68 mmol) of 2-[4-(5-chloro-2-cyanophenyl)-5-methoxy-2-oxopyridin-1(2H)-yl]butanoic acid (racemate) and 404 mg (purity 31%, 0.75 mmol, 1.1 eq.) of 3-chloro-1H-indazole-5-amine were reacted according to General Method 1. The combined crude products were purified by repeated preparative HPLC (Reprosil C18, water/acetonitrile gradient). Yield: 18 mg (purity 94%, 13% of theory) of the title compound Example 196 and 65 mg (55% of theory) of the title compound Example 197, which was isolated as a by-product due to the starting material 3-chloro-1H-indazole-5-amine employed being contaminated with 1H-indazole-5-amine.
