実験手順

Trans-2-(2-methylpyrazolo[1,5-a]pyridin-4-yl)cyclopropanecarbaldehyde (1.62 g, 8.08 mmol), 8 M aqueous sodium hydroxide solution (4.04 mL, 32.3 mmol) and hydroxylamine hydrochloride (1.85 g, 26.7 mmol) was dissolved in ethanol/water (65 mL/13 mL), and the mixture was stirred at 60° C. for 3 hr. The reaction solution was concentrated, extracted with ethyl acetate, washed with saturated brine, and dried over anhydrous sodium sulfate, and the solvent was evaporated under reduced pressure to give the title compound (1.67 g, yield 96%).
