Procedure

To a solution of Compound 239F (13.6 g, 45.1 mmol) in 10 mL of dry THF was added a solution of TBAF (67.6 mL, 67.6 mmol) in THF. The mixture was stirred overnight at room temperature. Water was added and the reaction mixture was extracted with EtOAc (250 mL×3). The combined organic layers were washed with brine and dried over anhydrous Na2SO4. Concentration in vacuo followed by flash chromatography (hexane-EtOAc: 1:1 to 1:2) on silica gel afforded 6.03 g (Yield: 75%) of 239H as an oil.
