実験手順

A solution of Example 263A (2.8 g, 9.44 mmol) in tetrahydrofuran (200 mL) was cooled to 0° C. and sodium hydride (0.34 g, 14.17 mmol) was added. The mixture was stirred at 0° C. for 30 minutes and (2-(chloromethoxy)ethyl)trimethylsilane (2.5 mL, 14.17 mmol) was added. The mixture was warmed to room temperature, stirred for 2 hours, quenched with brine and extracted with ethyl acetate (twice). The organic phase was concentrated and purified by flash chromatography (silica gel, 30% ethyl acetate in hexane) to afford the title compound. MS (ESI+) m/z 427 (M+H)+.
