Vorschrift
The residue from Step D is dissolved in 50 ml of THF and added to 3.8 g (0.1 m) of LiAlH4 in 50 ml of THF dropwise. The mixture is refluxed for one hour after completion of the addition. The mixture is cooled and sufficient saturated aqueous Na2SO4 solution is added to quench the excess LiAlH4. Methylene chloride and solid anhydrous Na2SO4 is added and the mixture is filtered. Concentration provides the crude product.
