Procedure

A mixture of Example 263B (2.5 g, 5.86 mmol), zinc cyanide (0.8 g, 7.0 mmol), 1,1′-bis(diphenylphosphino)ferrocene (0.4 g, 0.7 mmol) and tris(dibenzylideneacetone)dipalladium(0) (0.27 g, 0.3 mmol) in N,N-dimethylformamide (50 mL) and water (0.5 mL) was flushed with nitrogen and heated at 80° C. overnight. The reaction was 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 326 (M+H)+.
