A solution containing 1-{[5-(2-chloro-5-iodophenyl)-1,2,4-oxadiazol-3-yl]methyl}-2-propyl-4-(trifluoromethyl)-1H-indole-5-carbonitrile (Example 291) (0.378 g, 0.662 mmol), 1,1-bisdiphenylphosphinoferrocene (0.073 g, 0.132 mmol), E3N (1.0 mL, 13.6 mmol), Pd(OAc)2 (0.032 g, 0.132 mmol), anhydrous MeOH (2.0 mL) and anhydrous DMF (20 mL). The mixture was then stirred at 70° C. under a carbon monoxide atmosphere for a period of 4 h and then allowed to cooled to rt. The reaction was partitioned between NaHCO3 and EtOAc, dried (MgSO4) and concentrated to dryness. The mixture was purified on a biotage prepak column (0-10% EtOAc-hexanes gradient) to give 0.214 g (64% yield) of pure product: MS (ES) m/z 502 (M+).
