実験手順

A mixture of Example 10B (0.417 g, 0.94 mmol), tert-butyl acrylate (0.26 mL, 1.74 mol) and triethylamine (0.7 mL, 5 mmol) in DMF (3 mL) was degassed with nitrogen for 45 minutes, treated with PdCl2(o-tol3P)2 (0.032 g, 0.046 mmol), and heated to 80° C. overnight. The resulting mixture was cooled to room temperature, then partitioned between water and ethyl acetate. The organic extract was washed with brine, dried (Na2SO4), filtered, and concentrated. The residue was purified by flash column chromatography on silica gel with 30% ethyl acetate/hexanes to provide 0.25 g (61% yield) of the desired product. MS (ESI(+)) m/e 445 (M+H)+.
