Versuchsvorschrift

To a solution of (4-(1-(2,6-difluorophenyl)-4-methoxy-1H-pyrazolo[4,3-c]pyridin-3-yl)phenyl)acetonitrile (148.1 mg) obtained in Step A of Example 39 in DMF (5 mL) was added NBS (77 mg) at 0° C., and the mixture was allowed to be warmed to room temperature, and stirred overnight. The reaction mixture was poured into water, and the mixture was extracted twice with ethyl acetate. The organic layers were combined, washed with saturated brine, and dried over sodium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (161 mg).
