   أخرىThe residue was purified by column chromatography (elution solvent: hexane/ethyl acetate=10/1, 4/1, 2/1)

الإجراء التجريبي

The same operation as in Example (90a) was performed using tert-butyl 3-hydroxy-4,4-dimethoxypiperidine-1-carboxylate (5.2 g, 20 mmol), sodium hydride (55% content, 1.31 g, 30 mmol), allyl iodide (5.03 g, 30 mmol) and DMF (50 mL). The residue was purified by column chromatography (elution solvent: hexane/ethyl acetate=10/1, 4/1, 2/1) to obtain 5.64 g of the title compound as a colorless oily substance (93%).
