Vorschrift

A mixture of 54 g (134 mmol) N-[4-iodo-6-(4-methyl-piperazin-1-yl)-pyridin-3-yl]-2,2-dimethyl-propionamide, 420 ml toluene, 150 ml 2 N sodium carbonate solution, 4.63 g (3.9 mmol) tetrakis(triphenylphosphine)palladium(0) and 20.16 g (147 mmol) o-tolylboronic acid was heated under argon at 80° C. for 12 h. After cooling to room temperature, the aqueous phase was separated and washed twice with toluene. The combined organic layers were washed with 50 ml brine, dried (sodium sulfate), evaporated and dried in vacuo to yield 49 g (quantitative) of the title compound as a brown oil.
