Versuchsvorschrift
To a stirred and cooled (0° C.) solution of 8.00 g (26.7 mmol) of the product of Step A dissolved in 50 mL of anhydrous THF was added 53.3 mL (53.3 mmol) of a 1M solution of lithium aluminum hydride in THF. After the addition was complete the reaction mixture was allowed to warm to room temperature and stirred 2 hours. The stirred reaction was then quenched by dropwise addition of 2.5 mL water, then 2.5 mL of 15% NaOH, and finally 7.5 mL water. The reaction mixture was then filtered and concentrated in vacuo. The residue was dissolved in ethyl acetate, washed with 1N HCl, saturated NaHCO3, dried (MgSO4), and evaporated in vacuo to afford 4.0 g (53%) of the title compound.
