Reaction Steps

To a mixture of 5,6-dichloro-1H-indole (1.0 g, 5.37 mmol), Cu(OTf)2 (194 mg, 0.537 mmol) in DCM (15 mL) at RT, ethyl 2-diazoacetate (918 mg, 8.05 mmol) was added dropwise. The resulting mixture was stirred at RT for 16 h, quenched with water, and then extracted dichloromethane. The organic layer was dried over Na2SO4, filtered and concentrated in vacuo. The residue was purified by Prep-HPLC to afford the desired product (120 mg, 8.2% yield) as light yellow solid. ESI-MS m/z: 272.1[M+H]+.
