Versuchsvorschrift

To a mixture of 3-(N-isopropyl-3-(trifluoromethyl)phenylsulfonamido)benzoic acid (155 mg, 0.4 mmol) and 1-hydroxybenzotriazole hydrate (61 mg, 0.4 mmol) in dichloromethane/N,N-dimethylformamide (4:1, 6 mL) was added 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide (EDC, 62 mg, 0.4 mmol) in dichloromethane (1 mL). After 5 minutes, (R)-octahydropyrrolo[1,2-α]pyrazine (50 mg, 0.4 mmol) in dichloromethane (1 mL) was added. The mixture was stirred at room temperature overnight. Then the mixture was concentrated. The residue was diluted with ethyl acetate (100 mL), washed with water (2×20 mL), dried over sodium sulfate, and concentrated. The residue was purified by chromatography on silica gel (dichloromethane, then methanol/dichloromethane=1:12) to give the titled compound: 1H NMR (300 MHz, DMSO-d6) δ ppm 1.00 (d, 6H, J=8 Hz), 1.35 (m, 1H), 1.65-2.10 (m, 6H), 2.80-3.05 (m, 4H), 3.45-3.55 (m, 1H), 4.40-4.50 (m, 1H), 4.60 (m, 1H), 6.98 (s, 1H), 7.15 (m, 1H), 7.50 (m, 2H), 7.88 (m, 2H), 8.10 (m, 2H); MS (ESI) m/z 496 (M+H)+.
