実験手順
76 mg (purity 82%, 0.15 mmol) of 2-{4-[5-chloro-2-(difluoromethoxy)phenyl]-5-methoxy-2-oxopyridin-1(2H)-yl}-4-methoxybutanoic acid (racemate) and 25 mg (0.17 μmol, 1.1 eq.) of 5-aminobenzimidazolone were reacted according to General Method 1. The crude product was purified by preparative HPLC (Reprosil C18, water/acetonitrile gradient). Yield: 37 mg (45% of theory)
