Versuchsvorschrift
Intermediate 2A was prepared as described in Intermediate 1A using 5-chloro-2-iodopyridine. The racemate was purified by preparative SFC chromatography (Berger SFC MGII, CHIRALCEL® OJ-H 250×30 mm ID, 5 μm, 80/20 CO2/MeOH, 85 mL/min) to give Intermediate 3A. RT=3.44 min (H2O/CH3OH with TFA, CHROMOLITH® ODS S5 4.6×50 mm, gradient=3 min, wavelength=220 and 254 nm); MS(ES):m/z=497 [M+H+].
