実験手順

A mixture of Example 201A (10.40 g, 38.4 mmol), tert-butyldimethylsilyl chloride (6.07 g, 40.3 mmol), and imidazole (5.49 g, 80.6 mmol) in DMF (75 mL) at room temperature was stirred for 16 hours, treated with water (300 mL), and extracted with diethyl ether (3×400 mL). The combined extracts were washed with brine (100 mL), dried (Na2SO4), filtered, and concentrated. The concentrate was purified by flash column chromatography on silica gel with 10% ethyl acetate/hexanes to provide the desired product.
