実験手順
To a suspension of 1-benzenesulfonyl-1H-pyrrolo[2,3-b]pyridine (6.0 g, 23.3 mmol) in dry tetrahydrofuran (300 mL) at −78° C. was added n-butyllithium in n-hexane (1.6 M, 10 mL, 16 mmol). The mixture was stirred at −78° C. for 5 min and then treated with 4-methylsulfanylbenzaldehyde (2.4 g, 15.8 mmol) dropwise. The resulting mixture was stirred at −78° C. for 1 h and quenched with brine. The mixture was extracted with ethyl acetate (2×500 mL), washed with brine, dried over anhydrous sodium sulfate and concentrated in vacuo. The residue was washed with dichloromethane (2×5 mL) and dried in vacuo to afford (1-benzenesulfonyl-1H-pyrrolo[2,3-b]pyridin-2-yl)-(4-methylsulfanyl-phenyl)-methanol (7.0 g, 73%) as a white solid: LC/MS m/e calcd for C21H18N2O3S2 [M+H]+ 411.52, observed 411.3.
