Reaktionsschritte
Lithium aluminum hydride (2.5 equiv.) is added to a stirred solution of compound (7). Reduction is complete within 15-20 minutes. The mixture is hydrolyzed with a solution of potassium hydrogen sulfate in water. Ether is added and the aqueous phase is separated and extracted. The organic phases are combined, washed with 1N HCl saturated sodium hydrogen carbonate and saturated sodium chloride, and dried with magnesium sulfate. The solvent is evaporated to leave the desired product
