Reaction Steps

To a suspension of lithium aluminum hydride (1.18 g, 31.0 mmol) in tetrahydrofuran (70 mL) was added a solution of trans-2-(2-methylpyrazolo[1,5-a]pyridin-4-yl)cyclopropanecarbaldehyde oxime (1.67 g, 7.76 mmol) in tetrahydrofuran (8 mL) at room temperature, and the mixture was stirred at room temperature for 1.5 hr. Sodium sulfate decahydrate (17 g) was added under ice-cooling, and the mixture was filtered through celite. The filtrate was concentrated under reduced pressure to give the title compound (1.39 g, yield 89%).
