In the field of pharmaceuticals and agrochemicals, for example, bilimidine derivatives have high affinity for endothelin receptors as endothelin antagonists (Japanese Patent Application Laid-Open Nos. 221223/1991, 162449/1991, and 449/1992). — 1 94972, JP-A-11-92458) are disclosed.

Among them, 2,5-dipyridylsilole, which has a 2-pyridyl group as an aryl group, has an extremely high electron transporting property, and this electric transporting property is one of the best electron transporting materials to date.

Figure imgf000017_0001
As is evident from Table 3, the reaction is significantly more marked by the addition of a co-catalyst (ligand) such as a 2- (2-pyridyl) pyrimidine derivative than by a conventional reaction using only a copper catalyst. Accelerated and high yield and high purity of the target compound can be obtained.
