Reaction Steps

To a solution of product of Example 136A (0.8 g, 2.76 mmol) in N,N-dimethylformamide (10 ml) were added Zn(CN)2 (0.18 g, 1.52 mmol) and Pd(Ph3)4 (0.32 g, 0.28 mmol) and stirred at 120° C. for overnight. The crude product was purified by flash column chromatography using 0%, 5% and 10% of ethylacetate in hexanes to yield 0.28 g (44%) of product. MS (ESI+) m/z 233 (M+H)+;
