実験手順

After dissolving N-cyclopropylmethyl-N-[7-(2-methoxy-4,6-dimethylphenyl)-2-(methylsulfanyl)pyrazolo[1,5-a]pyridin-3-yl]amine (100 mg) in tetrahydrofuran (2 mL), tetrahydro-2H-4-pyrancarbaldehyde (78 mg) [CAS No. 50675-18-8] and sodium triacetoxyborohydride (87 mg) were added, and the mixture was stirred for 1 hour. Saturated aqueous sodium hydrogencarbonate was added to the reaction mixture, extraction was performed with ethyl acetate, and the extract was washed with brine. After drying over anhydrous magnesium sulfate and filtration, the solvent was concentrated under reduced pressure, the residue was purified by silica gel column chromatography, and the title compound (70 mg) was obtained from the n-hexane:ethyl acetate (7:1) fraction as a yellow oil.
