Versuchsvorschrift

Triethylamine (0.038 mL) and chloronicotinic acid hydrochloride (20 mg) were added to a solution of N-cyclopropylmethyl-N-[7-(2-methoxy-4,6-dimethylphenyl)-2-(methylsulfanyl)pyrazolo[1,5-a]pyridin-3-yl]amine (33 mg) in dichloromethane (0.8 mL) while cooling on ice, and the mixture was stirred at the same temperature for 1 hour. Saturated aqueous sodium hydrogencarbonate was added while cooling on ice, extraction was performed with ethyl acetate, and the extract washed with brine, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate:n-hexane=3:2) to obtain the title compound (36 mg) as white crystals.
