A tetrahydrofuran solution (35 ml) in which ethyl 4-cyano-5-methyl-4-(3-thienyl)hexanoate (6.66 g) was dissolved was added dropwise to a tetrahydrofuran solution (50 ml) of lithium aluminum hydride (686 mg). After stirring for 2 hours, 2N aqueous NaOH and water were added to treat the mixture, and the resulting precipitates were filtered. The resulting filtrate was evaporated, and the residue was purified by silica gel column chromatography (ethyl acetate/hexane system), to give the title compound as a yellow oil (5.30 g, 95%).
