실험 절차

The title product of Example 22(5.0 g, 34.0 mmol) in 40 mL of tetrahydrofuran was added dropwise to a stirred suspension of lithium aluminum hydride (LiAlH4, 3.2 g, 85.0 mmol) in 100 mL of THF over 20 minutes. The reaction was brought to reflux for 2 hours, cooled to 10° C., and treated with water (33.2 mL), 15% NaOH (3.2 mL), and then water (9.6 mL) again. The mixture was filtered and the solid was washed with Et2O. The filtrate was dried (Na2SO4), filtered, and stripped of solvent to yield 4.0 g of crude product that was distilled to produce the title compound (340 mg).
