Procedure

A solution of 7-(4-chlorophenyl)-2-methyl-1H-pyrrolo[2,3-c]pyridine (170 mg, 0.07 mmol) prepared in Example 463, dimethylamine (2.0M tetrahydrofuran solution; 375 μl, 0.75 mmol), acetic acid (0.36 ml) and formaldehyde (0.68 ml) in ethanol (10 ml) was refluxed for 60 hours. The reaction mixture was concentrated under reduced pressure. The resulting residue was diluted with a sodium hydroxide solution and 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=1/5, v/v) to give 85 mg of the titled compound as a white solid.
