Versuchsvorschrift

A mixture of 3-bromo-4-fluoro-N-(4-(trifluoromethoxy)phenyl)benzamide (Stage 1.2, 100 mg, 0.264 mmol), 3-methylpyrrolidine-3-ol hydrochloride (72.8 mg, 0.529 mmol), and TEA (147 μL, 1.058 mmol) in DMSO (199 μL) was stirred at 90° C. for 16 h. Additional TEA (73.7 μL, 0.529 mmol) was added to the mixture and stirring was continued for 72 h at 100° C. The cooled RM was diluted with TBME/EtOAc (1:1)(30 mL), sequentially washed 0.5 M HCl (3×5 mL), brine (5 mL) and then evaporated to dryness under reduced pressure. The crude product was purified by flash chromatography (RediSep® Silica gel column, 12 g, cyclohexane/EtOAc-EtOH+0.1% NH4OH (9:1), from 20% to 60% EtOAc-EtOH+0.1% NH4OH (9:1)) to yield the title compound as a white solid.
