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 3,4-dichlorophenylboronic acid instead of 4-fluorophenylboronic acid, to the title compound (18 mg, 10%) which was obtained as a white solid. MS (ESI): m/e=369.9 [M+H]+.
