Reaction Steps

A solution of 104 g of 2,5-dibromopyrimidine, 100 g of 4-benzoxyphenylboronic acid, 4.75 g of Pd (10% on activated charcoal), 4.5 g of triphenylphosphene and 93 g of sodium carbonate in 1 l of toluene, 0.5 l of ethanol and 0.3 l of water is heated at 80° C. for 24 hours. After filtration, the organic phase is separated off and evaporated to dryness in vacuo. The residue is recrystallized from acetonitrile: 83 g of solids of melting point 153°-155° C.
