Procedure
After dissolving N-[7-(4-bromo-2-methoxyphenyl)-2-(methylsulfanyl)pyrazolo[1,5-a]pyridin-3-yl]-N,N-dicyclopropylmethylamine (60 mg) in N,N-dimethylformamide (0.26 mL), zinc cyanide (31 mg) and tetrakis (triphenylphosphine)palladium (0) complex (23 mg) were added, the mixture was heated and stirred at 95° C. for 12 hours and then cooled to room temperature, and ethyl acetate was added. After filtering out the precipitated insoluble portion, extraction was performed with ethyl acetate. The obtained organic layer was washed with water and dried over magnesium sulfate, and the solvent was distilled off under reduced pressure. The obtained residue was purified by silica gel column chromatography (ethyl acetate:n-hexane=1:8) to obtain the title compound (32 mg) as a yellow oil.
