Procedure
A mixture of Example 177A (40 mg, 0.05 mmol) and 1M tetrabutylammonium fluoride in THF (130 uL, 0.13 mmol) in THF (3 mL) at room temperature was stirred for 3 hours, treated with 1M HCl (10 mL), and extracted with 5% methanol in ethyl acetate (3×20 mL). The combined extracts were washed with brine (5 mL), dried (Na2SO4), filtered, and concentrated. The concentrate was purified by flash column chromatography on silica gel with 20% methanol/ethyl acetate to provide the desired product.
