YieldReaction ConditionsOperation in experiment
100% Sodium hydroxide (4.1 g, 102.8 mmol) was added to a solution of tetrabutylammonium bromide (331 mg, 1.0 mmol) and 5-bromo-1H-pyrrolo[2,3-b]pyridine (6.7 g, 34.7 mmol) in dichloromethane (80 mL) at 0 C. The mixture was stirred at 0 C. for 5 min. Benzene sulfonyl chloride (5.7 mL, 44.5 mmol) was added to the above mixture slowly at 0 C. The resulting mixture was stirred at 0 C. for 15 min before it was warmed to 25 C. and kept stirring at that temperature for 12 h. The reaction mixture was filtered and the filtrate was concentrated in vacuo and then washed with hexanes to afford 1-benzenesulfonyl-5-bromo-1H-pyrrolo[2,3-b]pyridine as a white solid (11.8 g, 100%): LC/MS m/e calcd for C13H10BrN2O2S [M+H]+ 338.20, observed 337.1, 339.1; 1H NMR (400 MHz, CDCl3) delta ppm 6.56 (d, J=4.0 Hz, 1H), 7.51 (m, 2H), 7.60 (m, 1H), 7.75 (d, J=4.0 Hz, 1H), 7.98 (d, J=2.1 Hz, 1H), 8.18 (m, 2H), 8.45 (d, J=2.0 Hz, 1H).
