실험 절차

To a stirred suspension of lithium aluminum hydride (1.84 g, 48.6 mmol) in diethyl ether (50 mL) at ambient temperature was added a solution of 4-(4-chlorophenyl)butanamide in tetrahydrofuran (25 mL), dropwise over 8 minutes. Stirring was continued at ambient temperature for a further 4 hours. The reaction mixture was carefully quenched by sequential slow addition of water (2 mL), 10M sodium hydroxide (0.75 mL), and water (7 mL). After stirring the mixture for 20 minutes, it was extracted with diethyl ether (50 mL). The organic layer was dried over sodium sulfate and concentrated to afford 4-(4-chlorophenyl)butan-1-amine as a light yellow oil (1.36 g, 61%).
