Reaktionsschritte

A solution of the 2,6-difluoro-4-{[(1S*,2R*)-2-(1-methyl-1H-pyrazol-5-yl)cyclopentyl]oxy}benzenesulfonamide (0.23 g, 0.65 mmol) prepared in Example 111c, 2,4-difluoropyrimidine (0.23 g, 1.96 mmol) and potassium carbonate (0.36 g, 2.61 mmol) in DMF (6.5 mL) was stirred at 120° C. for 3 hours. After allowing to cool, water (50 mL) was added to the reaction solution, followed by extraction with ethyl acetate (50 mL). The thus obtained organic layer was washed twice with water (50 mL) and dried over anhydrous sodium sulfate. After vacuum concentration, the residue was purified with silica gel chromatography (ethyl acetate/methanol=6:1) to yield the title compound (150 mg, 51%) as a colorless amorphous solid.
