Versuchsvorschrift

To 3-(chlorosulfonyl)benzoyl chloride (0.474 g, 1.98 mmol) in anhydrous dichloromethane (10 mL) was added (S)-octahydropyrrolo[1,2-α]pyrazine (0.250 g, 1.98 mmol) in dichloromethane (4 mL) slowly over 10 minutes at room temperature. Then sodium carbonate (0.420 g, 3.96 mmol) was added. The mixture was stirred at room temperature for 5 hours. Then 2,6-difluoroaniline (2.56 g, 19.81 mmol) was added. The mixture was stirred at room temperature overnight and then concentrated. The residue was purified by chromatography on silica gel (dichloromethane, then methanol/dichloromethane=1:10) to give the title compound.
