Versuchsvorschrift
As described for Example 3, 4-(1H-imidazol-4-yl)-5-methyl-3-(4-fluorophenyl)-isoxazole (73 mg, 0.3 mmol) was converted, using 4-cyanophenylboronic acid instead of 4-fluorophenylboronic acid, to the title compound (13 mg, 13%) which was obtained as an off-white solid. MS: m/e=345.3[M+H]+.
