2-Dicyclohexylphosphino-2',6'-di-i-propoxy-1,1'-biphenyl (75 mg, 0.16 mmol) and palladium (II) acetate (18.08 mg, 0.08 mmol) were dissoved in toluene (2 mL) at ambient temperature. The mixture was degassed and purged with nitrogen and warmed to 50°C for 20 mins. In a separate vessel, were mixed tert-butyl piperazine-1-carboxylate (300 mg, 1.61 mmol), 7-bromo-1H-indole (316 mg, 1.61 mmol) and sodium-t-butoxide (296 mL, 2.42 mmol) in toluene (3 mL). The mixture was degasssed and purged with nitrogen and warmed to 50°C. The catalyst solution was added to the reaction vessel and the resulting mixture was degassed and purged with nitrogen and heated at 100°C for overnight. UPLC analysis showed virtually no reaction (only 7% conversion to product). Reaction abandoned.
