Procedure
The ester thus obtained was further reduced by aluminum hydride (prepared from 760 mg of lithium aluminum hydride and 880 mg of aluminum chloride) in 7 ml of ether. After completion of the reaction, ethyl acetate was added to the reaction mixture, and the precipitate was filtered off. The filtrate was evaporated to dryness, yielding 3.5 g of the desired product.
