実験手順

A −30° C. solution of Example 17A (0.1 g, 0.41 mmol) and N-methylmorpholine (0.03 mL, 0.41 mmol) in THF (5 mL) was treated dropwise with acetyl chloride (0.03 mL, 0.41 mmol), stirred for 1 hour, warmed to 0° C. over 1 hour, quenched with water, and extracted twice with ethyl acetate. The combined extracts were washed with brine, dried (MgSO4), filtered, and concentrated to provide 111 mg of the desired product. Rf=0.24 (5% methanol/dichloromethane).
