Procedure
As described for Example 3, 4-(1H-imidazol-4-yl)-5-methyl-3-phenyl-isoxazole (112.6 mg, 0.5 mmol) was converted, using 3-chloro-4-fluorophenylboronic acid instead of 4-fluorophenylboronic acid, to the title compound (8 mg, 5%) which was obtained as a white solid. MS (ESI): m/e=353.9 [M+H]+.
