Reaction Steps

7-(3,4-dihydro-1H-isoquinolin-2-yl)-1-(4-fluorobenzyl)-2,3-dimethyl-1H-pyrrolo[2,3-c]pyridin-5-carbonitrile (300 mg, 0.73 mmol) prepared in Example 690 was diluted with a mixture of ethanol (7 ml) and water (1 ml). Potassium hydroxide (410 mg, 7.3 mmol) was added to the solution, which was then refluxed for 72 hours. 1N hydrochloric acid was added to the reaction mixture, which was then extracted with ethyl acetate. The 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/n-hexane=1/1, v/v) to give 250 mg of the titled compound as a white solid. (Yield: 81%)
