74.0 mg (127 μmol) of tert-butyl 4-({2-[4-(5-chloro-2-cyanophenyl)-5-methoxy-2-oxopyridin-1(2H)-yl]-3-[2,2-difluorocyclopropyl]propanoyl}amino)benzoate (mixture of racemic diastereomers) and 195 μl (2.53 mmol) of TFA were reacted according to General Method 2. The crude product was purified by preparative HPLC [column: Chromatorex C18, 10 μm, 125 mm×30 mm, mobile phase: acetonitrile/water gradient (0 to 3 min 15% acetonitrile, to 35 min 90% acetonitrile and a further 3 min 90% acetonitrile)]. Yield: 45 mg (52% of theory)
