Versuchsvorschrift

To as solution of 1-(4-pyridinyl)-3-hydroxypyrrolidine (330 mg, 2.01 mmol) in dichloromethane (30 mL) was added methanesulfonic acid (0.15 mL, 2.31 mmol). After 15 seconds, quinoline (0.3 mL, 2.54 mmol) was added, immediately followed by a toluene solution of phosgene (0.65 mL, 1.25 mmol). After 5 minutes, the reaction was placed in an oil bath at 35° C. After 45 minutes, the reaction was cooled to room temperature. N-(5-Chloropyridin-2-yl)-2-aminobenzamide (498 mg, 2.01 mmol) was added, followed by quinolin (0.3 mL, 2.54 mmol). After stirring overnight, the reaction was diluted with dichloromethane (150 mL) and washed with saturated aqueous sodium carbonate (2×25 mL). The organic layer was concentrated in vacuo and purified by flash column chromatography (100% CH2Cl2 to 9% MeOH/CH2Cl2) and then by HPLC to give the title product (181 mg, 0.41 mmol, 21%).
