실험 절차
The nitrile 20A (3 g, 12 mmol) dissolved in 50 ml of diethyl ether was added dropwise to a mixture of LiAlH4 (912 mg, 2 equiv.) in diethyl ether (80 mL) and stirred at 0° C. Then, the mixture was stirred at room temperature overnight. The excess of LiAlH4 was destroyed by water addition at 0° C., the solid formed was filtered, washed with Et2O and the filtrate was dried over Na2SO4 and evaporated to dryness to obtain 2.5 g of the amine as a yellow oil. The amine was used for the following step without purification.
