Reaction Steps

To a mixture of 5-bromo-6-chloro-1H-indole-3-carbaldehyde (445 mg, 1.72 mmol), Bis(tert-butylcarbonyloxy)iodobenzene (961 mg, 2.30 mmol) in isopropyl acetate (2 mL) was added methanesulfonamide (111 mg, 1.15 mmol). After stirring 5 minutes, Bis[rhodium(α,α,α′,α′-tetramethyl-1,3-benzenedipropionic acid)] (18.3 mg, 0.0230 mmol) was added and heated to 50° C. for 2 h. The reaction was filtered and the collected solid (245 mg) was identified as a mixture of the title compound and 5-bromo-6-chloro-1H-indole-3-carbaldehyde. The mixture was taken forward without any further purification.
