実験手順

Sodium borohydride [1.89 g (50 mmol)] was added to a solution of 2.82 g (10.0 mmol) of 4-(3-phthalimidopropyloxy)pyridine in 150 ml of ethanol. The mixture was stirred at room temperature for 15 minutes. After the solvent was distilled off, brine was added to the residue. The mixture was extracted with chloroform and dried over anhydrous magnesium sulfate, and then the solvent was distilled off. The residue was purified by column chromatography (eluent: ethanol/ethyl acetate=1:10), and then recrystallized from ethyl acetate to obtain 1.54 g of the desired compound (yield: 54.2%, colorless crystals).
