Reaktionsschritte

Palladium (II) acetate (0.075 g, 0.34 mmol) and racemic-2,2'-Bis(diphenylphosphino)-1,1'-binaphthyl (0.223 g, 0.36 mmol) were suspended in dioxane (5mL). The mixture was evacuated and purged with nitrogen, and warmed to 50°C. In a separate vessel, 2-bromo-4-iodo-1-methoxybenzene (1.4 g, 4.47 mmol), (tetrahydro-2H-pyran-4-yl)methanamine (0.547 mL, 4.47 mmol) and sodium-t- butoxide (0.645 g, 6.71 mmol) were suspended in dioxane (5ML). The resulting mixture was evacuated, purged with nitrogen and warmed to 50°C. After ~30 mins, the catalyst mixture was transferred to the reaction vessel. The reaction was evacuated and purged with nitrogen and heated at 80°C overnight. Very little product and mainly SM so reaction abandoned.
