실험 절차

To a degassed mixture of tert-butyl 3-[4-(5,5-dimethyl-1,3,2-dioxaborinan-2-yl)phenyl]pyrrolidine-1-carboxylate (85 mg, 0.237 mmol), 5-bromo-6-chloro-1H-indole-3-carbaldehyde (67.3 mg, 0.26 mmol) and 2N aqueous potassium carbonate (0.47 mL, 0.94 mmol) in toluene (1.12 mL) and ethanol (0.38 mL) was added [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II) (17.3 mg, 0.0237 mmol). The reaction mixture was heated to 120° C. in a microwave for 30 min. The reaction mixture was partitioned between water and EtOAc. The EtOAc layer was washed with brine, dried over Na2SO4 and concentrated in vacuo. The residue was purified by preparative thin-layer chromatography (EtOAc/petroleum ether=1:2) to give tert-butyl 3-[4-(6-chloro-3-formyl-1H-indol-5-yl)phenyl]pyrrolidine-1-carboxylate (40 mg) as a yellow solid.
