Reaction Steps

To a rt solution of 26.B (341 mg, 0.63 mmol) in CH2Cl2 (5 mL) was added TBAF (available from Aldrich) (1.0 M, 3.2 mL, 3.2 mmol). The resulting mixture was stirred at rt for 12 hr, treated with water (15), and extracted with 30% iPrOH/CHCl3 (3×15 mL). The combined organic layers were washed with water, brine and dried over MgSO4. After removal of organic solvent under reduced pressure, purification of the residue by flash chromatography on silica gel using 0-10% MeOH/CH2Cl2 for elution gave the title product 26.C as colorless solid (141 mg, 71%).
