実験手順

To 3-{[(3-fluorophenyl)amino]sulfonyl}benzoic acid (0.9 g, 3.05 mmol) and 2-(3H-[1,2,3]triazolo[4,5-b]pyridin-3-yl)-1,1,3,3-tetramethylisouronium hexafluorophosphate(V) (1.27 g, 3.35 mmol) in N,N-dimethylacetamide (6.4 mL) and 2-methyltetrahydrofuran (15 mL) was added (S)-octahydropyrrolo[1,2-a]pyrazine (0.55 g, 4.33 mmol) in 2-methyltetrahydrofuran (4 mL). The reaction was stirred at ambient temperature overnight and then diluted with 2-methyltetrahydrofuran (15 mL). The organic solution was washed with 6% NaHCO3/6% NaCl (10 mL), and the aqueous layer was extracted with 2-methyltetrahydrofuran (15 mL). The combined organic layers were washed with 6% NaHCO3/6% NaCl (10 mL), saturated NaCl (2×10 mL, 2×20 mL) and 1:1 saturated NaCl/water (2×20 mL), and then concentrated. The residue was concentrated from ethanol (2×10 mL) to give the title compound.
