실험 절차

To a solution of methyl 5-fluoro-2-methyl-3-indenyl-acetate (24 g) in dry THF (300 ml) lithiumaluminum hydride (6.9 g) is added. The mixture is stirred at room temperature for 1.5 hours. Excess LiAlH4 is destroyed with saturated aqueous NaHSO4 solution. The organic phase is concentrated in vacuo, and the crude product is purified via silica gel column chromatography elution with methylene chloride. The residue is recrystallized from hexane to give 5-fluoro-2-methyl-1H-3-indenyl-(2-hydroxy) ethane (yield 63%; m.p. 65°-66.5° C.).
