実験手順

To a solution of 2-Bromo-4-{(S)-1-[(R)-1-(4-methoxy-phenyl)-ethyl]-pyrrolidin-2-yl}-pyridine (160 mg, 0.44 mmol) in a mixture of toluene (9 mL) and ethanol (3 mL) are added 3-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-indole-1-carboxylic acid tert-butyl ester (228 mg, 0.66 mmol), Pd(PPh3)4 (51 mg, 0.04 mmol) and sodium carbonate (2N) (0.7 mL, 1.40 mmol). The reaction mixture is stirred at 85° C. overnight, cooled to room temperature. Water and EtOAc are added to the mixture. The layers are separated and the aqueous layer is extracted with EtOAc. The combined organic layers are washed with brine, dried over Na2SO4, filtered and concentrated down. The crude product is purified by flash chromatography on silica gel (EtOAc/Hexane: 10%˜90%) to give 3-(4-{(S)-1-[(R)-1-(4-Methoxy-phenyl)-ethyl]-pyrrolidin-2-yl}-pyridin-2-yl)-indole-1-carboxylic acid tert-butyl ester as a yellow solid (175 mg, 79%). M/Z=498.32 [M+1]
