Versuchsvorschrift

To a solution of approximately 7.26 g (2.6 mmol) of the crude product of Step D, dissolved in 50 mL of anhydrous THF was added 26 mL (2.6 mmol) of tetra-n-butylammonium fluoride and the reaction mixture was stirred at room temperature for 16 hours. The mixture was then evaporated in vacuo and the residual oil was purified on a silica gel flash chromatography column eluted with 5% methanol/chloroform to afford 3.386 g (79%) of the title compound as a colorless oil.
