実験手順
The product from Step B was reacted with sodium hydride (0.220 g, 60% dispersion in oil, 5.4 mmol) and n-propyl iodide (0.375 mL, 3.85 mmol) according to the procedure described in Example 7, Step C. The crude product was chromatographed on silica gel with 30% ethyl acetate in hexane. The title compound was obtained as a foam, (0.400 g).
