Reaction Steps

Lithium diisopropylamide (0.88 mL, 1.52 mmol, 1.8M in heptane/THF/ethylbenzene) was added to a solution of 3-methyl-1-(phenylsulfonyl)-1H-pyrrolo[2,3-b]pyridine (0.20 g, 0.734 mmol) in THF (4.0 mL) at −78° C. The slurry was stirred at −78° C. for 30 minutes, and then methyl iodide (0.059 mL, 0.952 mmol) was added. The reaction mixture was allowed to warm up to room temperature and stirred for 2 hours. Water was then added to the mixture followed by dichloromethane. The layers were separated. The aqueous layer was extracted twice with dichloromethane. The organic layers were dried with sodium sulfate, filtered and concentrated in vacuo. The crude was purified by flash chromatography to afford 2,3-dimethyl-1-(phenylsulfonyl)-1H-pyrrolo[2,3-b]pyridine (0.17 g, 99%) as a solid (purity 80%).
