実験手順

To a solution of N-cyclopropylmethyl-N-[7-iodo-2-(methylsulfanyl)pyrazolo[1,5-a]pyridin-3-yl]-N-tetrahydro-2H-4-pyranylmethylamine (50 mg) dissolved in a mixture of 1,2-dimethoxyethane (2 mL) and water (1 mL) was added 2,6-dimethoxy-4-(methoxymethyl)phenylboric acid (50 mg), tetrakis(triphenylphosphine)palladium(0) (40 mg) and barium hydroxide octahydrate (56 mg), and the reaction mixture was heated and stirred for 3 hours at 80° C. Water and ethyl acetate were added to the obtained reaction mixture, insoluble residue was filtered out with celite, and the filtrate was extracted with ethyl acetate. The organic extracts were combined and washed with brine, dried over anhydrous magnesium sulfate and filtered, and the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography and then by column chromatography using NH Silica (Fuji Silysia) to afford the title compound (36 mg) as a yellow oil.
