Procedure

A mixture of 0,05 M of 4-(trans-4-pentylcyclohexyl)bromobenzene, 0,06 M of 2,6-difluoropyridine-3-boronic acid, 1,25 g of Pd(PPh3)4, 100 ml of toluene, 40 ml of ethanol and 50 ml of 2 M Na2CO3 -solution is heated at 60 ° C under stirring for 2 hours. Customary work-up and recrystallisation from ethanol gives 2,6-difluoro-3-[4-(trans-4-pentylcyclohexyl)phenyl]-pyridine with C 58° N 107° I.
