Reaction Steps

To a mixture of 6-chloro-5-[4-(1-hydroxycyclobutyl)phenyl]-1H-indole-3-carbaldehyde (40 mg, 0.123 mmol), Bis(tert-butylcarbonyloxy)iodobenzene (104 mg, 0.256 mmol) in isopropyl acetate (2 mL) was added methanesulfonamide (12 mg, 0.126 mmol). After stirring 5 minutes, Bis[rhodium(α,α,α′,α′-tetramethyl-1,3-benzenedipropionic acid)] (5 mg, 0.007 mmol) was added and heated to 80° C. overnight. The mixture was concentrated to give a crude residue, which was purified by preparative HPLC to afford the title compound (6.6 mg, 13%) as a yellow solid.
