反応手順
300 mg (796 μmol) of 2-[4-(5-chloro-2-cyanophenyl)-5-methoxy-2-oxopyridin-1(2H)-yl]-4-methoxybutanoic acid (racemate) and 231 mg (876 μmol, 1.1 eq.) of tert-butyl 6-amino-2-methyl-3-oxo-2,3-dihydro-1H-indazole-1-carboxylate were reacted according to General Method 5A. The crude product was purified by flash chromatography (silica gel 50, cyclohexane/ethyl acetate mixtures). Yield: 229 mg (46% of theory)
