Reaction Steps

247 mg (558 μmol) of tert-butyl 2-[4-(5-chloro-2-cyanophenyl)-5-methoxy-2-oxopyridin-1(2H)-yl]-3-(1-methylcyclopropyl)propanoate (racemate) in 1 ml of dichloromethane and 859 μl (11.2 mmol) of TFA were reacted according to General Method 6A. The crude product was purified by preparative HPLC [column: Chromatorex C18, 10 μm, 125×30 mm, mobile phase: acetonitrile/0.1% formic acid gradient (0 to 3 min 10% acetonitrile, to 35 min 90% acetonitrile and a further 3 min 90% acetonitrile)]. Yield: 95 mg (43% of theory)
