Procedure

When 7-chloro-2-(4-bromomethylphenyl)benzoxazole, 5,7-dichloro-2-(4-bromomethylphenyl)benzoxazole and 4-(benzoxazole-2-yl)-1-bromobenzocyclobutene are used in place of 2-(4-bromomethyl-3-fluorophenyl)benzoxazole in the above example, there is obtained 4-(7-chlorobenzoxazol-2-yl)-phenylacetonitrile, 4-(5,7-dichlorobenzoxazol-2-yl)phenyl-acetonitrile, and 4-(benzoxazol-2-yl)-1-cyanobenzocyclobutene, respectively.
