실험 절차

The synthesis was performed with reference to the known literature (US 2006/0148801). A solution of 6-methyl-1-tosyl-1H-pyrrolo[2,3-b]pyridine (0.17 g, 0.60 mmol) in ethanol (5.0 mL) was added with 5 N aqueous sodium hydroxide (1.0 mL), and the mixture was refluxed for 8 hours by heating. The solvent was evaporated under reduced pressure, the residue was extracted with chloroform, and then the organic layer was washed successively with water and saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure, and then the residue was subjected to silica gel column chromatography (eluted with hexane/ethyl acetate (80:20→60:40)) to obtain 6-methyl-1H-pyrrolo[2,3-b]pyridine (0.071 g, 90%).
