실험 절차

A solution of Example 75B (900 mg, 4.39 mmol) in tetrahydrofuran (10 mL) was cooled under argon with an ice bath and treated with a 2M solution of benzyl magnesium chloride in tetrahydrofuran (6.6 mL, 13.16 mmol). The reaction was stirred overnight at room temperature followed by the addition of one more equivalent of benzyl magnesium chloride. The mixture was heated at 70° C. for 9 hours. One more equivalent of benzylmagnesium chloride was added, and the reaction was heated at 70° C. for another 90 minutes and was allowed to cool to room temperature. Aqueous saturated ammonium chloride was added, and the product was extracted with ethyl acetate and purified by silica gel column chromatography using 30% ethyl acetate in hexanes to afford the title compound. MS (ESI+) m/z 237.1 (M+H)+.
