実験手順
To a solution of 1-(phenylsulfonyl)-3-(1-(phenylsulfonyl)-1H-imidazol-2-yl)-1H-indole (10ya) (5.0 mmol) in anhydrous THF (100 mL) at −78° C. was added 1.7 M tert-butyllithium in pentane (1.2 equiv, 6.0 mmol) and stirred for 10 min. A solution of 3,4,5-trimethoxybenzoyl chloride (1.2 equiv, 6.0 mmol) in THF was added at −78° C. and stirred overnight.2 The reaction mixture was quenched with 100 mL of saturated NaHCO3 solution (aqueous) and extracted by ethyl acetate (300 mL). The organic layer was dried over magnesium sulfate and concentrated. The residue was purified by flash column chromatography (hexane:ethyl acetate 3:1) to give a white solid. Yield: 30%. 1H NMR (500 MHz, CDCl3) δ 8.09 (d, J=10 Hz, 1H), 8.04 (d, J=10 Hz, 2H), 7.91 (s, 1H), 7.76 (d, J=5 Hz, 2H), 7.65 (t, J=10 Hz, 1H), 7.55-7.58 (m, 5H), 7.40 (s, 2H), 7.33-7.36 (m, 3H), 7.25 (t, J=10 Hz, 1H), 4.05 (s, 3H), 4.03 (s, 6H). MS (ESI) calcd for C33H27N3O8 657.0. Found 680.1 [M+Na]+.
