Versuchsvorschrift

A solution of Example 417A (142 mg, 0.5 mmol) in THF (3 mL) at room temperature was treated with 60% sodium hydride in oil (40 mg, 1.0 mmol) and methyl iodide (0.30 mmol), stirred for 30 minutes, adjusted to pH<7 with 4M HCl in dioxane (0.5 mL), filtered, and concentrated. The concentrate was purified by flash column chromatography on silica gel with 10% ethyl acetate/hexanes to provide the desired product.
