실험 절차

To a mixture of 3-{[(2-fluorophenyl)amino]sulfonyl}benzoic acid (800 mg, 2.71 mmol) and 2-(3H-[1,2,3]triazolo[4,5-b]pyridin-3-yl)-1,1,3,3-tetramethylisouronium hexafluorophosphate(V) (1133 mg, 2.98 mmol) in N,N-dimethylacetamide (6.5 mL) and 2-methyltetrahydrofuran (19.5 mL) was added (R)-octahydropyrrolo[1,2-a]pyrazine (479 mg, 3.79 mmol). The reaction was stirred at room temperature for 3 hours, diluted with 2-methyltetrahydrofuran (5 mL), and washed with saturated bicarbonate (2×25 mL). The combined aqueous layers were adjusted to pH 7 with buffer and re-extracted with 2-methyltetrahydrofuran (3×15 mL). The combined organic layers were concentrated under reduced pressure. The residue was taken up in ethanol (25 mL) and concentrated to give the title compound.
