Procedure

66 mg (0.11 mmol) of tert-butyl 4-[(2-{4-[5-chloro-2-(difluoromethoxy)phenyl]-5-methoxy-2-oxopyridin-1(2H)-yl}4-methoxybutanoyl)amino]benzoate (racemate) were hydrolysed with TFA according to General Method 2. The crude product was purified by preparative HPLC (Reprosil C18, water/acetonitrile gradient). Yield: 31 mg (52% of theory)
