実験手順

120 mg (0.19 mmol) tert-butyl 4-{3-[(3R)-3-({1-[5-(4-hydroxyphenyl)pyridin-3-yl]-3-methoxy-3-oxopropyl}carbamoyl)piperidin-1-yl]-3-oxopropyl}piperidine-1-carboxylate were dissolved in 2.11 ml tetrahydrofurane. 126 mg (0.39 mmol) cesium carbonate and 64 mg (0.37 mmol) 1-iodo-2-fluoroethane were added. The mixture was stirred at room temperature for 70 hours. 64 mg (0.37 mmol) 1-iodo-2-fluoroethane were added and the mixture stirred at room temperature for 48 hours. 64 mg (0.37 mmol) 1-iodo-2-fluoroethane were added and the mixture stirred at room temperature for 70 hours. 64 mg (0.37 mmol) 1-iodo-2-fluoroethane were added and the mixture stirred at room temperature for 24 hours. 64 mg (0.37 mmol) 1-iodo-2-fluoroethane, 2 ml tetrahydrofurane and 126 mg (0.39 mmol) cesium carbonate were added and the mixture stirred at room temperature for 24 hours. 64 mg (0.37 mmol) 1-iodo-2-fluoroethane were added and the mixture stirred at room temperature for 24 hours, diluted with water and extracted with ethyl acetate. The organic phase was dried over sodium sulfate and concentrated in vacuum. Chromatography over 10 g silica gel (dichloromethane/ethanol 100/0-90/10) gave 84 mg (62%) tert-butyl 4-(3-{(3R)-3-[(1-{5-[4-(2-fluoroethoxy)phenyl]pyridin-3-yl}-3-methoxy-3-oxopropyl)carbamoyl]piperidin-1-yl}-3-oxopropyl)piperidine-1-carboxylate.
