Versuchsvorschrift

A solution of Example 113C (0.148 g, 0.351 mmol) and 5-(tributylstannyl)thiazole (0.184 g, 0.492 mmol), in N,N-dimethylformamide (1.3 mL) was degassed via nitrogen sparge for 5 minutes. The reaction was treated with bis(triphenylphosphine)palladium (II) chloride (0.025 g, 0.35 mmol) and heated at 100° C. for 6 hours. The reaction was cooled to ambient temperature, treated with water (20 mL) and extracted with ethyl acetate (80 mL). The aqueous layer was extracted with additional ethyl acetate (40 mL). The combined organic layers were washed with water (2×25 mL) and brine (25 mL), dried over anhydrous sodium sulfate, filtered, and concentrated under reduced pressure. The concentrate was purified by flash chromatography on a silica gel column, eluting with a gradient of from 0% to 50% ethyl acetae in hexanes, to provide the title compound as an off-white solid. MS ESI(+) m/z 470.2 [M+H]+.
