実験手順

1-Benzyl-7-(4-fluorobenzyloxy)-2,3-dimethyl-1H-pyrrolo[3,2-b]pyridine-6-carbonitrile (500 mg, 1.30 mmol) prepared in Example 276 was diluted with a mixture of ethanol (8 ml) and water (2 ml). Potassium hydroxide (650 mg, 13.0 mmol) was added to the solution, which was then refluxed for 24 hours. Water was added to the reaction mixture, which was then extracted with ethyl acetate. The separated organic layer was dried on anhydrous magnesium sulfate and then concentrated under reduced pressure. The resulting residue was purified with silica gel column chromatography (ethyl acetate/methanol=5/1, (v/v)) to give 280 mg of the titled compound as a white solid.
