実験手順

The reaction of 35 mmol of 2-(4-benzyloxy-2,3-difluorophenyl)-5-bromopyrimidine, 44 mmol of 2-octyloxypyridine-5-boronic acid, 70 mmol of sodium carbonate and 0.4 mmol of tetakis(triphenylphosphine)palladium(0) in 120 ml of toluene, 60 ml of ethanol and 60 ml of water is carried out analogously to the procedure indicated for Example 1a). Corresponding chromatographic purification and recrystallization from ethyl acetate gives 10.7 g (61%) of colorless crystals, m.p. 120° C., cl.p. 182-183° C.
