Versuchsvorschrift

To 2,4-dichloro-5-{[(2-fluorophenyl)amino]sulfonyl}benzoic acid (800 mg, 2.197 mmol) and 2-(3H-[1,2,3]triazolo[4,5-b]pyridin-3-yl)-1,1,3,3-tetramethylisouronium hexafluorophosphate(V) (919 mg, 2.416 mmol) in 2-methyltetrahydrofuran (15 mL) was added (R)-octahydropyrrolo[1,2-a]pyrazine (388 mg, 3.08 mmol). The reaction was stirred at room temperature for 45 minutes at which time N,N-dimethylacetamide (1 mL) was added. The reaction was stirred for an additional 45 minutes and N,N-dimethylacetamide (3 mL) was added. The reaction was stirred for an addition 2.5 hours, diluted with 2-methyltetrahydrofuran (15 mL), and washed with a solution of 6% sodium bicarbonate and 6% brine (2×15 mL). The aqueous layers were combined and re-extracted with 2-methyltetrahydrofuran (15 mL). The organic layer was washed with saturated brine (4×25 mL), dried over MgSO4, and concentrated. The residue was taken up in ethanol (20 mL) and reconcentrated to give the title compound.
